12.8.5 Active Mode Function
The Active Mode Function stops the motor according to the deceleration reference that is
preset in a parameter in the SERVOPACK when the safety request input signal turns OFF
during SBB-D or SPM-D.
If Profile Torque Mode or Cyclic Synchronous Torque Mode is set in controlword (6040h,
bits 4 to 9), the servo will be turned OFF and the motor will be stopped as soon as the
safety request input signal turns OFF.
The motor is stopped at the set deceleration rate (Pn622 or Pn623). After the decelera-
tion monitor time (Pc11 or Pc21) elapses, the servo is turned OFF (Switch ON Disable
state is entered).
