-
if the motor connections are OK, the problem is inside the controller;
replace it.
-
If the alarm occurs while the motor is running, check:
- motor
connections;
-
that the LC power contact closes properly, with a good contact;
-
if no problem is found, the problem is inside the controller. Replace it.
WAIT MOTOR STILL
(MDI/LED code = 45)
Cause:
The controller is waiting for the motor to stop rotating. This warning can only
appear in controllers for brushless motors.
WAIT MOT.P STILL
(MDI/LED code = 45)
Cause:
If DC Pump option is set to ON, the software expects the voltage on -P
output to be at a “steady state” value, before switching the LC on.
If the voltage is different, it could be due to the fact that the motor connected
to -P is not still. For this reason, the software waits 30 seconds for the
voltage to be at the “steady state” value (and for the pump motor to be still).
After this time, the software assumes that the problem is not due to the fact
that the pump motor is not still, and show the PUMP VMN NOT OK alarm.
Troubleshooting:
-
If the motor connected to -P is still moving, just wait for it to be still.
-
If not, in 30 seconds the alarm PUMP VMN NOT OK will appear.
WAITING FOR NODE
(MDI/LED code = 0)
Cause:
The controller receives from the CAN bus the message that another
controller in the net is in fault condition; as a consequence the controller itself
cannot enter into an operative status, but it has to wait until the other node
comes out from the fault status.
Troubleshooting:
Check if any other device on the CAN bus is in fault condition.
WARNING SLAVE
(MDI/LED code = 1)
Cause:
Warning on supervisor uC.
Troubleshooting:
Connect the Console to the supervisor uC and check which alarm is present.
WATCHDOG
(MDI/LED code = 8)
Cause
This is a safety related test. It is a self-diagnosis test that involves the logic
between master and supervisor microcontrollers.
Troubleshooting
This alarm could be caused by a CAN bus malfunctioning, which blinds
master-supervisor communication.
WRONG ENC SET
(MDI/LED code = 83)
Cause
Mismatch between parameters ENCODER PULSES 1 and ENCODER
PULSES 2 (see paragraph 8.2.5).
