22.10 SPD SUPERV EST
Defines the activation level for encoder supervision. The drive reacts according to
FAULT when:
• the estimated speed
• the filtered encoder speed* is lower than
Speed
*Filtered outcome of encoder 1/2 speed. Parameter
filtration coefficient for this speed.
**In normal operation, the filtered encoder speed is equal to signal
Encoder supervision can be disabled by setting this parameter to the maximum speed.

22.11 SPD SUPERV ENC
Defines the activation level for the encoder speed used in encoder supervision. See parameter

22.12 SPD SUPERV FILT
Defines the time constant for the encoder speed filtration used in encoder supervision. See parameter
