0
It defines will not be done the counting of operation time for change the filter system. Also resets the operation time
for filter maintenance alarm in P1052 parameter.

It defines the counting of operation time for filter maintenance alarm will be enabled and only will generate the alarm
message “A0770: Filter maintenance”, i.e., the CFW501 frequency inverter will continue control the motor.
2
It defines the counting of operation time for filter maintenance alarm will be enabled and will generate the alarm
message “A0770: Filter maintenance” during the motor deceleration and the fault “F0771: Filter maintenance” in the
CFW501 frequency inverter after stopping the motor.
