1-2 FM-STEPDRIVE/SIMOSTEP (FB)
The FM-STEPDRIVE is a power controller for controlling a Siemens
SIMOSTEP 3-phase stepping motor . The FM-STEPDRIVE has been
designed as a module for the SIMATIC S7-300 automation system.
The SIMOSTEP motor series includes the following 3-phase stepping
motors:

2-2 FM-STEPDRIVE/SIMOSTEP (FB)
The FM-STEPDRIVE power controller has interfaces, switches and
indicating elements arranged on the front panel as shown in figure 2-1.
The interfaces and parameter switches are visible when the front doors
are opened.
Figure 2-1 FM-STEPDRIVE power controller
Pulse interface The pulse interface can be used for controlling the power controller from
the master positioning unit using clock signals. With each clock pulse, the
motor moves one step. In addition, a PWM signal can be used for
adjusting the phase current of the stepping motor between 0 and 100 %.
Input signals: PULSE (clock), DIR (sense of rotation), ENABLE
(enables the amplifier), PWM (current control).
Output signal: READY1_N (readiness).
Signal interface The GATE_N input of the signal interface can be used for enabling or
disabling the clock signals for motor control fed to the PULSE input. The
ENABLE_N input has the same function as the ENABLE input for the
pulse interface although it is activated via 24 V. In addition, the ZERO
output can be used for evaluating the zero signal of the internal ring
counter.
Input signals: GATE_N (enabling/disabling the clock signal)
ENABLE_N (enables the amplifier)
Output signals: ZERO (ring counter zero signal), READY2
(readiness),
MSTILL (Motor standstill)
Mains and
intermediate circuit
connection
The mains connection supplies the power controller with 115 V or 230 V
AC. The intermediate circuit connection may be used for dissipating
surplus recovery energy of the motor.

Motor connection A 3-phase stepping motor of the SIMOSTEP series can be connected to
the motor connection.
Current and
parameter switches These switches are used for setting the motor phase current, the number
of steps (500, 1000, 5000, 10 000 steps/revolution) and the current
reduction
(to 60 % at motor standstill).
LED status
indicators To indicate readiness and any malfunctions (short-circuit between motor
phases, supply overvoltage/undervoltage, power controller
overtemperature, no GATE_N signal).
Fan A fan is installed in the FM-STEPDRIVE power controller.
The block diagram shown in figure 2-2 illustrates the most important
functional groups of the FM-STEPDRIVE power controller.
