Operation timing during Servo ON or OFF (when Servomotor is stopped)
*1. The Servo ON status will not occur until the Servomotor speed drops below approximately 30 r/min.
*2. The operation of the dynamic brake during Servo OFF depends on the Stop Selection with Servo OFF (Pn069).
*3. The Brake Interlock (BKIR) signal is output on the release request command that comes first, either from the Servo
Controller or the MECHATROLINK-II. The BKIR signal is used by assigning it to the general purpose outputs on
CN1.
Note The brake attraction and release time varies depending on the brake on the Servomotor. For details, refer
to 3-2 Servomotor Specifications on page 3-17.
