7-6 Brake Interlock
This function lets you set the output timing for the Brake Interlock Output (BKIR) signal that activates
the holding brake when the Servo is turned OFF or an error occurs.
It is also possible to use the controller to force the brake control via EtherCAT communications.
In the unit version 1.2 or later, you can select an output port from the brake output (BKIR) and a Gen-
eral Output (OUT 1 to 3). For the details on the connection method for when a General Output (OUT 1
to 3) is selected, refer to the wiring diagram in External Brake Interlock Output (EXTBKIR) on page
3-31.
Set an appropriate value to parameters described in 7-6-1 Objects Requiring Settings on page 7-22.

02 Timeout at Servo
OFF
Sets the time from when the OFF state of the operation
command is detected (the power supply to the motor is
OFF) until the Brake Interlock Output (BKIR) is turned
OFF (brake is held), when the Servo OFF is performed
during motor operation.
P. 9 -113
03 Threshold Speed at
Servo OFF
*2
Sets the motor speed at which the Brake Interlock Output
(BKIR) can be turned OFF (brake is held) after the Servo
OFF command is detected, when the Servo OFF is per-
formed during motor operation.
P. 9 -113
04 Hardware Delay
Time
Sets the delay time of the mechanical brake operation,
etc. Outputs the timing signal of the external brake by the
