The above diagram shows the action time of /BK signal and servo ON signal. Before
outputting /BK and brake is OFF, servo already power on; after not output /BK and brake
is ON, servo is OFF.
(4) Brake ON parameter (When servo motor is rotating)
The motor will power OFF when alarm occurs. The machine will move as gravity until the
brake action.
Set below parameters in order to use brake when motor speed decreases to setting value or
waiting time ends.
Set the brake time when servo OFF caused by /S-ON signal or alarm.
The brake is used to protect the position. The brake must be effective at suitable time
when servo motor stop. Users can adjust the parameters according to the machine action.
The /BK signal from ON to OFF under either of the following conditions:
1. Motor speed drops below the value of P5-07 after servo OFF.
2. over the time of P5-08 after servo OFF.
The real speed is max speed (P3-09) even set the speed higher than max in P5-07.
