F8011 Commutation Offset Could Not Be Determined - Bosch Rexroth IndraDrive Troubleshooting Manual

Rexroth IndraDrive

F8011 Commutation offset could not be determined

Cause
Axis could not carry out required motion
During commutation setting process, axis got into
resonance
Motor has not been supplied with current
Sine-wave method without success, although axis
has required freedom of motion and doesn't show
any resonance phenomena
Signals of motor encoder do not reflect motion
process of axis; encoder cables of 2 drives possibly
mixed up
- or -
Incorrect polarity of encoder signals

LSA Control S.L. www.lsa-control.com comercial@lsa-control.com (+34) 960 62 43 01
Supported by Firmware Variant:
The sine-wave method for commutation setting could not determine any
value for the commutation offset.
Remedy
Check axis for stiffness or blocking; if necessary, reduce
friction (lubrication, guiding device of trailing cable
installation) or remove blocking
- or -
Set "search direction for sine-wave method" to "increase
of amplitude with priority" in P-0-0522, Control word for
commutation setting
- or -
Increase value in P-0-0506, Amplitude for angle
acquisition, in order to increase excitation amplitude for
sine-wave method compared to frictional force of axis
Set "search direction for sine-wave method" to "increase
of frequency with priority" in P-0-0522, Control word for
commutation setting
- or -
Reduce value in P-0-0507, Test frequency for angle
acquisition in order modify excitation frequency for
sine-wave method compared to resonance frequency of
axis
Check motor connection
Try with manually input values if automatic search for
motor-specific values for P-0-0506, Amplitude for
angle acquisition and P-0-0507, Test frequency for
angle acquisition doesn't provide any result in spite of
several repetitions
Check motor encoder signals. To do this move motor
knowing manufacturer-side setting for sense of rotation
or velocity polarity and check actual position values with
regard to polarity and plausibility.
