SAFETY NOTICE!
Position control systems are inherently hazardous. Even a small motor, if
coupled to a leadscrew, gearbox, or any other form of mechanism that
provides a mechanical advantage, can generate considerable force and
could cause serious injury. Incorrect operation can also lead to damage to
the motor or associated machinery. It is essential that the purpose of the
various fault detection features built into the SimStep’s PM600 controller be
fully understood and used correctly.

SimStep Manual - 3400 Iss. D 7th June 2004 page 3
1 Description
The system is a single axis stepper motor control and drive rack. Motor motion is
commanded either from a computer or from a terminal via the RS232 (or RS485) serial
data port or from a manual Jog Box or Joystick controller. The controller can drive stepper
motors in open-loop (step counting) mode or encoded motors/mechanisms in closed-loop
mode.
The controller consists of:
1MSE570-Evo2 3.5A Stepper Drive
1PM600 Motor Controller
1MSB867 Backplane
1MSE779 Power Supply Board
These are mounted in a 3U high 28HP rack unit. The SimStep is supplied with a mains
lead, an RS232 cable and an RS232 terminator. A range of standard motor, encoder,
limits/datum and I/O cables are available.
Fig.1.1 SimStep Front View
The system has a PM600 controller and a MSE570 Stepper drive powered by a power
supply based on the MSE779 power supply board.
The PM600 controller and the MSE570 plug into the MSB867 backplane. Step, clock and
direction signals from the PM600 are fed to the MSE570 Stepper drive. The bipolar
stepper motor is connected to the MSB867 backplane via a rear panel connector.

SimStep Manual - 3400 Iss. D 7th June 2004 page 4
The PM600 position controller generates the clock and direction signals for the MSE570
drive in response to move commands.
The PM600 enable output is connected to the enable input of the MSE570 drive. If the
PM600’s enable output is turned off (e.g. as a result of an error) the motor current will
turned off. The enable output may be turned off by an AB abort command, or reset (turned
on) by an RS command (see Section 6.4).
The Idle output from the PM600 is connected to the current reduction input on the
MSE570 to reduce the motor current to about 25% when the motor is not moving.
An incremental encoder can be fitted to the motor or mechanism to monitor the movement
of the mechanism. The quadrature signals from the encoder are connected to the PM600
to allow passive closed-loop operation. The system is initially supplied with the PM600
configured for open-loop operation. The PM600 must be reconfigured for closed-loop
operation (see Section 8.2).
The MSB867 has a multi-axis jog receiver; it allows the PM600’s Jog inputs to be
controlled by a JC809 Jog Box. The axis addresses shown on the JC809 may be
changed by altering the settings of the rotary switches accessible by removing the top
cover of the unit.
The power supply provides +24V (nominal) to energise the supply rail on the PM600
controller, and +40V (nominal) to energise the supply rail on the MSE570 drive.
The PM600 manual referred to in this document can be found on www.mclennan.co.uk.
1.1 Rear View:
Fig.1.2 SimStep Rear Panel
Connections for motors, limits/datum, I/O, encoders, RS232 and mains are taken from the
MSB867 backplane to connectors on the rear panel.

SimStep Manual - 3400 Iss. D 7th June 2004 page 5
The mains input is a filtered IEC inlet.
The MOTOR connector has outputs from the PM570-Evo2 stepper drive to connect to a
bipolar stepper motor.
WARNING! Serious damage will occur if the motor is connected or disconnected
whilst the power is switched on. Allow 30 seconds after switching off.
The LIMITS/DATUM connectors have inputs for the Upper and Lower Limit switches, a
Datum Approach switch and a Datum Stop switch. The connections to the Limit switch
inputs must be made for normal operation of the PM600 controllers.
Limit switches must not be used as a safety device or part of a safety system for
ensuring the safety of persons
The ENCODER connector is for the position encoder input. It has a +5V supply to
energise the encoder, complementary quadrature inputs and complementary index inputs.
The JOG A and JOG B connectors have inputs for Jog pushbuttons, a Joystick control
and data connections for a JC809 Jog Box.
They have connections for Jog, Jog- and Jog Fast pushbuttons compatible with a JC100
Jog Box and +5V, 0V Joystick input and Joystick centre tap compatible with a JC400
Joystick. The JC100 and JC400 may be plugged into either connector.
If using a JC809 Multi axis jog box, the axis address that is assigned to Jog is set on the
MSB867 interface board using a rotary switch (see section 5.2). The JC809 can be
connected to other axes by using a ‘Jog daisy-chain’ cable plugged into the vacant JOG A
or JOG B connector. The Jog Terminator supplied with the JC809 must be plugged into
the vacant connector in the last axis in the daisy-chain.
The I/O connector has inputs and outputs from PM600’s Read inputs and Write outputs.
There are also connectors for RS232 IN for connecting to the computer or terminal that
supplies the control data and RS232 OUT for connecting either to a subsequent control
rack (daisy-chain) or to an RS232 terminator. These connectors can also be configured for
RS485 communications (see section 1.2).
Note: The RS232 Terminator supplied with the control system must be fitted to the last
unit in the daisy-chain. This allows both replies from, and commands sent to, the controller
to be echoed back.
WARNING! To avoid overheating, the vents in the top and bottom of the unit must
be unobstructed at all times.

SimStep Manual - 3400 Iss. D 7th June 2004 page 6
1.2 Link Settings
The control operation of the SimStep can be configured by means of links fitted to the
MSE867. The links can be accessed by removing the rear top cover of the unit.
Fig. 1 Link Location
Link Action Default
LK1 Select automatic current reduction from PM600 idle output On
LK2 Drive over-temperature activates PM600 abort stop input On
LK3 Drive overload activates PM600 abort stop input On
LK4 to LK7 1-2 selects RS485, 2-3 selects RS232 RS232
LK8 Select internal (on) or external (off) abort stop Internal
LK1 If LK1 is on, the current to the motor will be reduced to about 25% of the current
set on the drive when the motor has finished its move and the controller returns to
Idle. The primary use of this function is to reduce the heating effect caused by the
motor. It is not intended to produce a precise holding-torque.
If LK1 is removed, the motor current will remain at the current set on the drive.
This setting is usually only needed when a high holding-torque is required. E.g.
when driving a mechanism with an offset load.
LK2 If LK2 is on, an over-temperature fault detected on the drive output stage will
cause the controller abort stop input to be activated.
LK3 Likewise if LK3 is on, an overload fault detected on the drive output stage will
cause the controller abort stop input to be activated.
LK4-7 These two position links select either the RS232 or RS485 communication
interfaces. When the links LK4 to LK7 are all in the 1-2 position, RS485 is selected
and when all in the 2-3 position, RS232 is selected.
If using RS485 communication, The last SimStep in the line should have SW3-8
on the PM600 switched to the ON position. This selects a 100Ωterminating
resistor. See figs 8.2 and 8.3 in section 8.3.
LK8 If LK8 is removed (off) the external ‘Abort Stop’ input selected. Pins 7 and 14 on
the Limits/Datum connector must be linked (via a normally-closed contact or
switch) to enable moves.

3 Cables
3.1 Motor and Limit/Datum cables
Motor and limit/datum cables fitted with connectors to plug into the rear panel of the
SimStep may be specified. The available lengths are shown below. The motor cables
have a connector on both ends, which can be connected either to the connector fitted to
the stepper motor or to the stepper motor wires via an MSA889 Junction Box.
Likewise, the Limit and Datum connections can be made either by connecting to the
socket on the end of the cable or via an MSA889 junction box. The connections to the
MSA889 junction box are shown in figures 4.2 and 4.3.
Fig. 3.1 Motor and Limit/Datum Cables
3.2 Electro-magnetic Compatibility (EMC)
The SimStep complies with EN-50081-1 and EN50082-1 when properly with cables that
use EMC connectors. The cable used to connect the motor to the drive should be a
screened, twisted pair type. The screen should be connected at both ends of the cable.
On the drive end, the screen should be connected to earthed metalwork of the case and
on the motor end, the screen should be connected to the motor body.
The EMC profile may be improved by fitting ferrite sleeves to the motor cables. For cable
diameters from 7mm to 8.5mm use RS part number 260-6492. For cable diameters from
8.5mm to 10mm use RS part number 309-7962.

4.3 Connection of Limits And Datum
Fig. 4.5 Limit/Datum Connections
All limit and datum signal inputs should utilise normally closed contacts.
Note* The datum approach signal is not always required. This is the case when:
a) The motor is operated at slow (creep speed) since it is not necessary to
decelerate before stopping at the datum point. In this case the datum
approach terminals should not be connected.
b) When the controller is configured to utilise the high-speed datum registration
feature. In this case, the datum approach connections should be linked.
Note ** This connection enables an external open contact to abort a move. However
for this feature to be utilised it is necessary to remove an internal link LK8
within the controller.
It should be noted that the limit switches should be placed sufficiently within the total travel
distance to allow the motor to decelerate from high speed.
They should also be mounted for sliding operation, so that they do not become crushed on
first use. No mechanism can decelerate instantaneously.

4.3.1 Datum Position
The datum position is detected as the datum stop switch opens. It is also summed with
the encoder index signal (if fitted). For further information, refer to the Datum Search
Strategies section (2.13) of the PM600 manual.
4.3.2 Using Over-travel limits as datum inputs.
In applications where space is limited, the over-travel
limit switches may also be used as the datum stop
switch. In the example shown the lower limit switch is
also connected to the datum stop input and the
controller is configured to utilise the high-speed
datum approach facility.

5 Power Supply Unit
The power supply unit used in this system has been designed to energise an MSE570
stepper drive and a PM600 Position Controller.
It provides the unregulated logic supply of +24V (nominal) to the PM600, and an
unregulated supply of +40V (nominal) to the MSE570.
There is a mains fuse fitted in the mains inlet, its rating is 2A anti-surge. There are two
front panel fuseholders that protect the DC outputs of the power supply. The rating of the
fuses are 3.15A for the motor rail and 1A for the logic rail.
The mains voltage may be changed from 230V to 115V by changing the position of the
links on the MSE779 PCB.
Fig. 5.1 Mains Voltage Selector

SimStep Manual - 3400 Iss. D 7th June 2004 page 17
6 MSE570 Stepper Drive
The MSE570 stepper drive translator is a 3.5A per phase bi-polar stepper drive.
The clock and direction signals from the PM600 controller are converted into chopped,
constant current drive levels to energise a bipolar stepper motor.
The step sequence is set to half step. Using a hybrid type stepper motor, 400 steps per
revolution will be obtained.
A thermal sensor protects the output devices in case of overheating. If the drive
temperature exceeds 80°C, the thermal sensor will operate. With the switch settings
shown below, the drive is disabled (SW1-1=on) and the condition is latched (SW1-2=on).
The latched condition can only be reset by removing the power.
