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.

Explanation
Set the time after a servo OFF command is
issued upon servo lock stop, until the brake
interlock output (BKIR) turns OFF and power
supply stops.
Set the time after a servo OFF command is
issued while the motor is moving, until the brake
interlock output (BKIR) turns OFF and power
supply stops. If the speed drops to or below the
value set in object 3439 hex before the time set
here, BKIR will turn OFF.
Set the speed at which to turn OFF power to the
Linear Motor when the Brake Interlock Output
(BKIR) signal turns OFF after execution of a
servo OFF command while the motor is moving.
If the time set in object 3438 hex elapses before
the motor drops to the speed set here, BKIR will
turn OFF.
This is the Set Brake Bit to force the brake
control via EtherCAT communications.
