STEPPER MOTOR MISM
This alarm occurs if the frequency
and the amplitude of the voltages
from the stepper motor lines are
mismatched in between In normal
condition when the amplitude of
the stepper motor lines increases,
the frequency of the stepper motor
lines must increase too.
It is necessary to replace
the controller.
220
MOTOR LOCKED
This alarm occurs if the current in
the steering motor stays close to
the maximum current longer than 1
sec.
Search for a mechanical
problem locking the motor.
To make easier the fault

MICRO SLAVE #4
It occurs in one of the following
conditions:
(Open loop application only) If the
slave uC detects the stator voltage
phasor rotates in the opposite
direction respect to the sign of the
stepper motor speed, this alarm
occurs. (Closed loop application
only) If the slave uC detects the
stator voltage phasor rotates in the
opposite direction respect to the
commanded position, this alarm
occurs.
It is necessary to replace
the controller.
222
FB POT LOCKED
In application with a feedback
potentiometer, this alarm occurs if
the feedback potentiometer (CPOT
on CNB#6) does not change (or
changes in the opposite direction)
its value even if commanded
to change. In application with
toggle switches with ENCODER
CONTROL to off, this alarm occurs
if the feedback encoder counting
does not change its value even if
commanded to change.
In application with the
feedback potentiometer,

mechanical block of the
steered wheel. Be sure the
wiper has not reached its
own electrical limit because
of too much angle of the
steered wheel. Besides,
this alarm may occur at
the installation when the
motor rotates in the wrong
direction turning away from
the wished
