11 - 04 Time Delay before Stopping the Auxiliary Motor Unit: 0.1
Settings 0.0 to 3600.0 sec Factory Setting: 0.0
 The number of Multi-function Output terminals set to 16, 17, 18 decides the number of auxiliary
motors. The maximum is three.
 The start/stop delay time can prevent the AC motor drive from overloaded during
starting/stopping.
 These parameters determine the starting sequence of auxiliary motors.
The auxiliary motor started first will be stopped first.
Example: Start sequence: motor 1 -> motor 2 -> motor 3
Stop sequence: motor 1 -> motor 2 -> motor 3
 The flowchart of auxiliary motor start/stop sequence:
Pr.11-01 Start-up frequency = 50 Hz, Pr.11-02 Stop frequency = 20 Hz
Pr.11-03 Time delay before start up = 10 sec, Pr.11-04 Time delay before stopping = 5 sec
