*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 value set in Stop Selection with
Servo OFF (Pn506).
*3 The Brake Interlock Output (BKIR) signal is output when a release request command is received from servo
control. The BKIR signal is allocated to the general-purpose output (CN1).
