P3.20.6 BRAKE FAULT DELAY (ID 352)
Use this parameter to set the brake fault delay time.
If the correct brake feedback signal is not received during this delay, a fault shows. This
delay is only used if the value of P3.20.1 is set to 2.
P3.20.7 RESPONSE TO BRAKE FAULT (ID 1316)
Use this parameter to set the response type to a brake fault.
P3.20.8 (P3.5.1.44) BRAKE FEEDBACK (ID 1210)
Use this parameter to set the brake status feedback signal from mechanical brake.
The Brake feedback signal is used if the value for parameter P3.20.1 is Enabled with brake
status supervision.
Connect this digital input signal to an auxiliary contact of the mechanical brake.
The contact is open = the mechanical brake is closed
The contact is closed = the mechanical brake is open
If the brake opening command is given, but the contact of the brake feedback signal does not
close in given time, a mechanical brake fault shows (fault code 58).

PUMP CONTROL
10.22.1 AUTO-CLEANING
Use the Auto-cleaning function to remove dirt or other material from the pump impeller. You
can also use the function to clear a blocked pipe or valve. You can use the auto-cleaning, for
example, in wastewater systems to keep the performance of the pump satisfactory.
