Vacon 100 - Pump Control; Auto-Cleaning

P3.20.8 (P3.5.1.44) BRAKE FEEDBACK (ID 1210)
This parameter includes the digital input selection for the status signal of the 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).
