9.5 Re sonance filter (motor controller CMMS-ST-C8-7-G2)
9.5.1 Function: Resonance filter
The resonance filter is only effective for motor controller CMMS-ST-C8-7-G2 with open loop (without
motor encoder/open loop). Resonance oscillations of the drive can be avoided with the resonance
filter. In the motor controller, three resonance speed ranges can be parameterised via the parameters
“speed”. and “band width”. If the drive reaches the parameterised resonance speed range during oper-
ation, this range will be skipped.
Speeds that have been parameterised as a resonance speed cannot be run constantly.
