Holding brake operation
*1 The servo does not turn ON until the motor rotation speed drops to approx. 30 r/min 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).
Note The brake application time and release time vary depending on the Servomotor brake. For details, refer to 3-3
Servomotor Specifications on page 3-36.
