Upon Servo ON,
if Deceleration stop (when Servo is OFF) : Method (No.224.0) = 3 (dynamic brake)
Upon Alarm Clear,
if Deceleration stop (when Servo is OFF) Method (No.224.0) = 3 (dynamic brake)
*1) SERVO does not turn ON until Motor Rotational Speed drops below 30 r/min.
*2) When DBRK output (No.224.3) = 1 (dynamic brake) after a stop per Deceleration Stop (when Servo is OFF)
