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:
1 MSE570-Evo2 3.5A Stepper Drive
1 PM600 Motor Controller
1 MSB867 Backplane
1 MSE779 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.

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.
