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
catching,
set DEBUG
OUTPUT to level 11.
221 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,
verify the feedback
potentiometer is not
mechanically loosened.
Check there is not a
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
