45 Delayed Spd Ref
One sample period delayed output of parameter 43 [S Curve
Spd Ref]. Used in some applications to phase synchronize the
speed reference value through SynchLink. This parameter
would be utilized in place of [S Curve Spd Ref] in the master
drive. [S Curve Spd Ref] would then be transmitted to the
slave drives over SynchLink. A value of 1.0 represents base
speed of the motor. Units:
