When the enable is OFF and the signal is true, lock the brake and delay the time P5-07 then close the
enable.
this setting is rotation detection TGON invalid time when motor stop.
The following diagram is the brake control output signal /BK and servo SON signal act time when
using the servo motor with brake.
Before outputting /BK to release the brake, 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 P5-08 after servo OFF.
2. over the time of P5-09 after servo OFF.
