*1. The Servo does not turn ON until the motor rotation speed drops to approximately 30 r/min or lower.
*2. The operation of the dynamic brake when the Servo is OFF depends on the set value in Stop Selection –
Disable Operation Option Code (3B20-02 hex).
*3. The Brake Interlock Output (BKIR) signal is output when a release request command is received from either
servo control or EtherCAT communications. The above example shows when there is no brake release
request from EtherCAT communications.
*4. Depends on the set value in Brake Interlock Output – Hardware Delay Time (4610-04 hex). The brake
attraction time and release time vary depending on the Servomotor brake. For details, refer to 3-2 Servomotor
