316 Configuration
Disabling the safety encoder interface
You must do the steps below to disable the FSE module in the FSO module
configuration. The drive is still using the measured motor speed data for the motor
control purposes if drive parameter 90.41 Motor feedback selection = Encoder 1 (in
an ACS880 drive) / 90.41 M1 feedback selection = Encoder 1 (in a DCS880 drive).
FSE module disabling steps:
1. Set S_ENCGEN. 01 = Disable
2. Set 91.11 = None
3. Set 200.232 = None
4. Set 200.231 = Disabled
5. Download the safety file to FSO module.
6. Make sure that the encoder-related parameters in drive parameter groups 91-92
are not locked any more. This indicates that FSO is not using the encoder.
7. Make sure that drive parameter 90.41 is set to Encoder 1 if motor control must still
use encoder data. If also drive must use speed estimate, 90.41 must be set to
Estimate. Note: Safe speed estimate cannot be used with a DCS880 drive.
