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.
