Operating Instructions, 09/2015, A5E36037884
Cause
After initializing the pole position using
track C/D, Hall signals or pole position
identification routine, the zero mark was
detected outside the permissible range.
For distance-coded encoders, the test is
carried out after passing 2 zero marks.
Fine synchronization was not carried out.
Encoder functionality is not operating cor-
rectly.
Fault status and fault number buffer are
inconsistent.
When the control mode is changed, the
drive must be saved and restarted.
One of positive torque limitation values
(P29050) becomes less than 0.
One of negative torque limitation values
(P29051) becomes greater than 0.
The electronic gear ratio (p29012[x] /
p29013[x]) exceeds the range from 0.02 to
200.
The electronic gear ratio (p29031[0] /
p29032[0]) exceeds the range from 0.02 to
200.
The servo motor with absolute encoder is
changed. Actual motor ID is different from
commissioned motor ID.
11.2 List of faults and alarms
Remedy
Check that the encoder cables are routed
•
in compliance with EMC.
Check the plug connections
•
If the Hall sensor is used as an equivalent
•
for track C/D, check the connection.
Check the connection of track C or D.
•
Replace the encoder or encoder cable.
•
Check the encoder type used (incremen-
•
tal/absolute) and the encoder cable.
If relevant, note additional fault messages
•
that describe the fault in detail.
Repower on.
Save and restart the drive.
Configure all of positive torque limitation val-
ues (P29050) not less than 0.
Configure all of negative torque limitation
values (P29051) not greater than 0.
Adjust the electronic gear ratio within the
permissible range from 0.02 to 200.
Adjust the electronic gear ratio within the
permissible range from 0.02 to 200.
The servo motor will be automatically config-
ured after the acknowledgement of this fault.
