Output (BKIR)
*1 The servo does not turn ON until the motor speed drops to approximately 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) 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).
