The actual current value amplitude resulting from commutation setting
with the saturation method is monitored. If it does not exceed a minimum
threshold when the command
P-0-0524, C1200 Commutation offset
setting command
is executed, the command error C1218 is generated.
Cause
Remedy
Actual current value amplitude is not sufficient for
exact determination of commutation offset
Increase signal voltage (
P-0-0506, Amplitude for angle
acquisition
) or reduce signal frequency (
P-0-0507, Test
frequency for angle acquisition
) and restart
commutation setting process
- or -
Enter value "0" in
P-0-0506, Amplitude for angle
acquisition
. Appropriate value for P-0-0506 is thereby
automatically determined during commutation setting
process
- or -
Reduce value of
P-0-0517, Commutation: required
harmonics component
, if approx. 30 similar values are
determined for
P-0-0521, Effective commutation
offset
with repeated commutation setting for different
motor positions (drive remains in "Ab"). Reduce
P-0-0517, Commutation: required harmonics
component
until command error C1218 no longer
occurs; finally check function several times!
Note:
If error occurs repeatedly, please contact our service
department.
