*1. The servo does not turn ON until the motor rotation speed drops to approx. 30 r/min or below.
*2. The dynamic brake operation when the servo is OFF depends on Stop Selection with Servo OFF (Pn506).
*3. The Brake Interlock output (BKIR) is output when the OR condition is met by a release request command from the
Servo control and from the MECHATROLINK-II. In the above example, the MECHATROLINK-II makes no release
request. The BKIR is assigned to the general-purpose output (CN1).
Note:The brake attraction time and release time vary depending on the Servomotor brake. For details, refer to "3-3
Servomotor Specifications" (P.3-32).
