This section shows the timing of the Brake Interlock Output (BKIR).
*1 The servo does not turn ON until the motor speed drops to approx. 30 mm/s or below.
*2 The operation of the dynamic brake when the servo is OFF depends on the setting of the Disable operation option code
(605C hex).
*3 The Brake Interlock Output (BKIR) signal is output either when a release request command is received via Servo controls
or when a release request command is received via EtherCAT communications. The above example shows when there is
no brake release request from EtherCAT communications. The BKIR is assigned to the general-purpose output (CN1).
