Sequence Circuit Configuration
Use these conditions to set the circuit for the open/close sequence of the holding brake:
•
Set the sequence-side operation conditions to activate terminal M1-M2 and open the holding brake.
•
Set the sequence to close the holding brake in an emergency if the drive detects a fault.
•
Set the sequence to open the holding brake when you enter an increase or decrease command.
