The SINUMERIK FM-NC has been implemented as a function module of the SIMATIC S7-300.


Configuring (PJ) 1.1 System landscape

04.95 07.94 10

FM-NC

The SINUMERIK FM-NC is a low-priced automation product for machine tools of the lower performance range. It consists of a SIMATIC S7-300 automation system and an NCU 570 function module, both of the same modular packaging system with which up to four axes/spindles can be controlled. The system can be expanded to control a fifth axis/spindle with the FM 354.

SIMATIC S7-300

The automation system consists of a U and different input/output devices fixed on a mounting channel. The construction is of the single- or multi-tier type, depending on the configuration. One SIMATIC S7-300 U can control up to four tiers with a maximum of eight bus s each (see Figure).

PLC

The S7-300 U and the connected digital or analog signal modules (SMs) together form the PLC area of the control. The U 314 can control a maximum of 512 inputs or outputs. Positioning axes can also be integrated in the PLC area if the system includes the relevant function modules (FMs).

NCU 570

The NC area consists of the NCU 570. The NCU 570 communicates

with the SIMATIC S7-300 U via serial I/O and communication bus, with up to four stepping motor drives via a 10 V interface with a maximum of four servo drives and/or via pulse interfaces,

with incremental or absolute measuring systems via four measuring circuit interfaces and

with operator s (OP), programmers (PG) and machine control s (M) of different performance classes via the multi-point serial interface (MPI). A 20-way front connector with point-to-point connections is used to connect:

2 probes 4 sensing elements, e.g. non- sensors 2 handwheels If necessary, the NC area can be expanded by configuring the NCU 570 to control an FM 354 via a local bus. In addition, signal modules can be controlled (the maximum configuration per tier must not be exceeded) to implement additional NC-specific inputs/outputs on the local I/O bus.

FM 354

The FM 354 communicates as an axis expansion module

via serial I/O bus with the NCU 570 via a 10 V interface with a servo drive and via a servo loop interface with an incremental or absolute measuring system.

PJ

The following can be connected with a 20-way front connector with single-wire terminals:

4 digital inputs 4 digital outputs FM STEPDRIVE

For several applications, it is possible to implement feed axes with low cost stepping drives. FM STEPDRIVE is a performance control for 3-phase stepper motors up to 15 Nm (SIMOSTEP). FM STEPDRIVE is actuated via the drive interface of NCU 570.

Power supply units

04.96 04.95 07.94 13

A power supply unit (PS 307) can be arranged to the left of the SIMATIC S7-300 U. It is connected to 230 V automating voltage on its primary side and provides 24 V direct voltage on its secondary side. The PS 307 can also be arranged in tiers 1 to 3 to the left of the IM module. The PS 307 is available in three versions:

S 24 V/2 A S 24 V/5 A S 24 V/10 A Single-tier construction

The single-tier construction consists of the S7-300 U, the NCU 570 and a maximum of seven modules (SM, FM). The SIMATIC S7-300 U drives all eight bus s and provides the logic power supply for their signal modules. The NCU 570 has its own power supply terminal for supplying its logic.

Multi-tier construction

In the multi-tier construction, an interface module (IM) must be arranged in tier 0 to the right of the S7-300 U. Beside the interface module, eight modules (SM, FM and the NCU 570) can be arranged. Tier 1 and each consecutive tier starts with an interface module (IM) and may incorporate another eight modules (SM, FM, NCU 570). Power supply to the logic is from the IM which has its own power supply terminal. One system may have a maximum of two NCU 570. In configuring the construction, the following parameters of the modules must be taken into :

S Mounting dimensions S Power inputs from 24 V S Power inputs from the 5 V I/O bus supply References:

Distributed arrangement

/S7H/, Manual

The multi-tier construction allows distributed arrangement of modules because the tiers can be connected by IM connecting cables with a maximum length of 10 m. For example, in the case of two-tier construction, signal modules can be arranged up to 10 m away from the NCU 570, in the case of four-tier construction up to 30 m.

Local P bus

The S7-300 U can usually address all 32 bus nodes via the serial I/O bus. However, the NCU 570 can interrupt this bus. This means that all modules positioned to the right of the NCU 570 can then only be addressed by the NCU 570 but not by the S7-300 U.

Configuring the mechanical construction

NCU 570 in the S7-300

PJ

The NCU 570 is installed in the SIMATIC S7-300 control as a function module. Adding the U 314 and input/output modules makes up the FM-NC control. Regarding the S7-300-U the NCU 570 behaves as a function module (FM).

Configuring the mechanical construction

The manual “SIMATIC S7; S7-300 Automation System; Configuring an S7-300” tells you which possibilities there are for configuring the mechanical construction and how to proceed. References:

/S7H/, Manual

Some additional information supplementing the instructions in the manual is given below.

Mounting position

Preference should be given to the horizontal mounting position. For the vertical mounting position, the necessary limitation of ambient temperatures should be taken into (maximum 40 °C).

Points to be observed when configuring the mechanical construction

When configuring the mechanical construction of your control which determines the mounting location of the NCU 570, the following rules should be followed: 1. A maximum of eight SMs or FMs (including the NCU 570 and FM 354) can be mounted in each tier. 2. This maximum number may be restricted by the width of the modules or the length of their mounting channel. The NCU 570 requires a mounting width of 200 mm, the FM 354 80 mm. 3. The maximum number is also restricted by the sum of the power input of all modules to the right of the U from the 5 V backplane bus supply. The U 314 can supply up to 1.2 A. The NCU 570 and the FM 354 each require 100 mA.

Installation of FM STEPDRIVE

The FM STEPDRIVE modules can be installed in addition to the eight SMs or FMs. They are not connected to the SIMATIC bus, therefore only the installation width required must be taken into .

Components and precautions

PJ

The FM-NC control is composed of several individual components each of which must be in accordance with EMC and the relevant safety standards:

Operator , consisting of monitor and MMC Machine control S7-300 with U and NCU 570 and FM 354 All load current circuits should be earthed to guarantee perfectly safe operation.

Earthed operation of S7-300

The reference potential (earth) of the S7-300 is earthed by means of a removable connection in the form of a jumper at the 24 V terminal block of the U. This jumper connects the ground (M) with the functional earth (PE) by making a low-resistance connection to the mounting channel. In the case of multi-tier construction, make sure that the earthing jumper is also fitted at all 24 V terminal blocks of the IM 361 R. The mounting channel is provided with an earth terminal for connection to the central earth bar inside the cabinet.

Measures for interference suppression In addition to the protective earthing of system components in accordance with VDE, special precautions must be taken to guarantee interference-free operation of the system. These measures include shielded signal cables, special equipotential bonding and earthing conductors.

Shielded signal cables

Only use specified cables according to the individual diagrams to ensure safe, interference-free operation of the system. As cable connectors the specified connector types only should be used. For signal cables, the shield must always have a conductive connection to both sides of the housings. Exceptions: 1. Standard shielded cables connected to one side only can be used for devices of other makes (printers, programmers, etc.). These devices must, however, not be connected to the control during normal operation. Whenever operation with devices of other makes is unavoidable, the shields must be connected to both housing sides. In cases like this, the device must additionally be connected to the control by means of an equipotential bonding conductor. 2. For analog signal (e.g. 10 V interface to the drive unit), one-sided connection of the shield to the control side should be preferred to suppress mains irradiation.

Installation of signal and load cables

04.95 07.94 29

In order to maintain the greatest possible noise immunity of the whole installation (control, power section, machine) the following EMC Guidelines must be observed:

The space between signal and load cables must be as great as possible. If necessary, signal and load cables can cross over (at an angle of 90°, if possible) but they should never run close together in parallel.

Signal cables from and to the NC and PLC should only be those offered by SIEMENS.

Signal cables must not be placed in the neighbourhood of strong external magnetic fields (e.g. motors and transformers).

High-current/high-voltage cables carrying pulses must always be led completely separate from all other cables.

If it is not possible to maintain an adequate distance between cables, signal cables must be shielded by laying them in cable ducts (metal).

The distance (interference irradiation area) between the following cables must be as small as possible:

!

–

Signal cable and signal cable

–

Signal cable and accompanying equipotential bonding conductor

–

Equipotential bonding conductor and protected conductor incorporated in the cable

SINUMERIK FM-NC control system

What is the NCU 570?

The NCU 570 is a microprocessor-controlled module for the position-controlled motion control of up to four axes/spindles for servo or stepping motor drives. Together with other system components it makes up the SINUMERIK FM-NC control system. Considered from the S7-300 U, the NCU 570 operates like a function module (FM).

Further system components

S7-300 U as PLC U, e.g. U 314 S7-300 signal modules (SMs) as input/output modules S7-300 interface modules (IMs) for system expansion S7-300 power supply modules (PS) for load current supply Operator s (OPs) or hand-held unit with MPI (Multi Point Interface) Machine control with MPI Programming devices with MPI (PGs) S7-300 function modules (FMs), e.g. positioning modules FM STEPDRIVE for activation of stepper motors

Use

Positioncontrolled motion control for servo axes

The NCU 570 enables the position-controlled motion control of up to four axes. Three of these axes can be dependent (interpolating). The NCU 570 provides for this purpose for each axis one analog output for the setpoint speed and one position encoder input for cyclic measurement of the actual position value. This is the way feed drives are normally controlled.

Spindle control

Spindles can be controlled by analog outputs by just setpoint speeds being output. A position encoder is not required.

Rotary axes

If the spindle position (angle of rotation) is measured by a position encoder, this spindle can be moved to an exact position like a servo axis (rotary axis operation).

Stepping motor control

In addition to the analog setpoint outputs, the NCU 570 is provided with pulse outputs for up to four stepping motor axes. In this case, the stepping motor is controlled via clock pulses. The number of pulses determines the position and their frequency the speed (velocity) of the spindle. The actual position value is not measured in controlled operation, the position controller considers the number of output pulses (setpoint position value) to be the actual value. To ensure exact positioning, the motor must not lose any steps.

Positioncontrolled stepping motor control

The NCU 570, having one position encoder input per axis, offers the possibility of operating stepping motors under position control like a servo axis.

Incremental measuring system

As a rule, position encoders are installed for position measurement. These supply counting pulses for the traversed path increments according to their resolution. Both rotary encoders and linear scales can be used for this purpose.

Reference point approach

To determine the absolute position of an axis, the control evaluates the zero mark of the incremental position encoder when a reference cam is overrun (cam connected to the PLC).

Absolute measuring system

Absolute encoders with serial interface can be connected instead of conventional incremental position encoders which only supply one measure for the path traversed. No reference point approach is required any more because these measuring systems always supply the absolute position as actual position value.

-Distance-coded re-

When linear scales with distance-coded reference marks are used as position encoders, measurement has to be performed across three marks only to determine the reference point because the control can establish the absolute position from these three distances.

ference marks

NC



07.94 53

Reference point approach with BERO

For stepping motor control, the zero pulse of a position encoder can be replaced by a proximity switch (BERO) attached to the shaft of the stepping motor and connected to the NCU 570.

Handwheel operation

The machine can also be operated “by hand” by connecting up to two handwheels which can be assigned to defined axes and the rotary movement of which is measured.

Measuring

Two probes can be connected and assigned to defined axes. In measuring mode, the actual position value is measured when a probe is reached during the traversing movement. References:

Stepping motor drives

07.94 62

Signals: One clock, directional and enable signal is provided for each channel as true and negated signal.

PULSE (CLOCK) The clock pulses serve to control the motor which performs one step with each rising pulse edge. The number of output pulses determines the angle of rotation, i.e. the path to be traversed. The pulse frequency determines the speed of rotation, i.e. the traversing velocity.

!

Important If your drive unit reacts to trailing clock edges, you must change the true for the negated clock signal when wiring. Otherwise discrepancies may result between the position calculated by the control and the actual position.

DIRECTION The output signal level determines the direction of rotation of the motor. ON signal: OFF signal:

“Counter-clockwise rotation” “Clockwise rotation”

Note If the direction of rotation of your motor should be other than stated above, your can reverse the direction of rotation via machine data. Make sure that the assignment of signal levels to the direction of rotation is correct by checking up in the Technical Documentation provided for your drive unit.

ENABLE The NCU 570 activates this signal when cyclic control operation is started. ON signal: OFF signal:

Enable power drive circuit One or several of the following reactions are possible, depending on the power section:

-

Disable pulse input De-energize motor Reset ring counter Cancel error message

Note The ENABLE signal is output together with the RF controller enable , i.e. you can also use the relay s as an alternative.

Stepping motor drives, continued Signal parameters All signals for stepping motor drives are output via differential signal line drivers in accordance with the requirements of the RS422 standard. The power section should be provided with differential signal receivers or optocoupler inputs enabling symmetrical pulse transmission for optimum interference immunity. Unsymmetrical transmission is also possible, but only for cable lengths of up to 10 m. All outputs are electronically protected against short-circuits and thermal overload.
