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.
*1 L4-07 = 0 [Speed Agree Detection Selection = No Detection during Baseblock] or During Frequency Output
Time Chart
Figure 12.3 shows the open/close sequence of the holding brake.
