The servo does not turn ON until the motor speed drops to approximately 30 mm/s or below.
*2
The Brake Interlock Output (BKIR) turns ON either when a release request is received via servo controls or
when a release request is received via EtherCAT communications. The above example shows when there is no
brake release request from EtherCAT communications.
The BKIR signal is assigned to the general-purpose output (CN1).
Note
After the error has been reset, the system enters the servo OFF state (motor not energized). To turn ON the
servo, send a servo ON command again after resetting the error, according to the above timing.
