7-5 Brake Interlock
This function lets you set the output timing for the brake interlock output (BKIR) that activates the
holding brake when the servo is turned ON, an error occurs, or the servo is turned OFF.
It is also possible to use the controller’s function to force the brake control via EtherCAT
communications. However, it is not supported on the OMRON Machine Automation Controller NJ-series
(Model: NJ501-100) and CJ1W-NC
81/82 Position Control Unit.
*1 The Brake Interlock Output (BKIR) is turned ON. The brake is released for a brake release command from either
EtherCAT communications or the Servo Drive.
*2 The Brake Interlock Output (BKIR) is turned OFF. The brake is engaged only when a set brake command is received from
both EtherCAT communications and the Servo Drive.
Applying the brake from EtherCAT communications is enabled only while the servo is OFF. If a Set Brake command is
received while the servo is ON, a Command Warning (B1 hex) will occur.
