Rockwell Automation Publication MMI-UM007F-EN-P - September 2020
The QSMC motor controller is
reporting a Soft Start Fault.
There is no voltage on the input to
turn on the soft start switch for
normal operation. The red power
LED is OFF during this condi-
tion.
This can be caused by an open or
short on the input power to the
motor controller.
A faulty contactor or power sup-
ply can also be the root cause.
Verify that the power supply is
operating properly.
Verify that the power wiring to
the controller is not damaged.
There is a fault within the soft
start circuit. The red power LED
is ON during this condition,
which indicates that there is input
voltage to the motor controller.
There is an anomaly downstream
of the soft start circuit that is load-
ing down the propulsion bus such
that the input capacitors cannot
charge.
This could be due to an internal
controller short, a propulsion
power cable short, or an internal
short in the motor proper.
Verify that the motor controller is
operating properly.
Verify that the stator drive cable is
not damaged.
Verify that the motor is operating
properly.
