Note: the value of So-16 should not be set too high, please use the Mfr’s value.
When servo motor stops or the motor speed is lower than So-16, if enable signal is OFF and electromagnetic
braking signal is invalid, after the time set by So-02, servo will be in the disable status.

Note: if some alarms occur, servo will turn to disable status, So-02 will be invalid.
b)
Braking when servo motor is rotating.
When servo motor is rotating and speed is higher than So-16, after alarm occurs, servo drive will become disable
status Immediate, servo motor will free stop. When any of below items occurs, braking signal will be closed:
1.
Speed decreases to setting value of So-16.
2.
Servo drive becomes disabled status, and after delay time of So-03.
