Motor Ctrl Ackn
Displays the Motor Control Processor's acknowledgment to the Velocity Processor for the Motor Control Command bits.

SrLss ZeroSpdLim
Functionally equivalent to Par 160 [Zero Speed Lim], but is used exclusively in
Sensorless speed mode. The value is automatically set from Par 3 [Motor NP Hertz], Par
4 [Motor NP RPM] or Par 7 [Motor Poles]. The automatic setting corresponds to the rated
slip speed of the motor (synchronous speed - nameplate speed). The value can be
manually set.

Set Speed Lim
Creates a tolerance - hysteresis band around the value in Par 41 [Limited Spd Ref] for
comparison to average speed feedback. The comparison controls bit 14 [At Setpt Spd] of
Par 155 [Logic Status]. In general bit 14 [At Setpt Spd] turns on when the feedback is
within the tolerance of the reference. Technically - Turn-on level for rising feedback = Par
41 [Limited Spd Ref] - Limit. Turn-off level for rising feedback = {Limited Spd Ref} +
2(Limit). Turn-on level for falling feedback = [Limited Spd Ref} + Limit. Turn-off level for
falling feedback = [Limited Spd Ref] - 2(Limit).

Creates a tolerance - hysteresis band around the value in Par 173 [Setpt1 TripPoint].
Turn-on level for ascending data = [Setpt1 TripPoint] - [Setpt 1 Limit]. Turn-off level for
ascending data = [Setpt1 TripPoint] + 2(Limit). Turn-on level for descending data =
[Setpt1 TripPoint] + Limit. Turn-off level for descending data = [Setpt1 TripPoint] - 2(Limit).

Setpt 2 Limit
Creates a tolerance - hysteresis band around the value in Par 176 [Setpt2 TripPoint]. For
positive setpoints: Turn-on level = [Setpt2 TripPoint], Turn-off level = [Setpt2 TripPoint] -
Limit. For negative setpoints: Turn-on level = [Setpt2 TripPoint], Turn-off level = [Setpt2
TripPoint] + Limit.

PI Lpass Filt BW
Sets the bandwidth of a single pole filter applied to the error input of the Process Control
regulator. The input to the filter is the difference between Par 181 [PI Reference] and Par
182 [PI Feedback]. The output of this filter is used as the input to the process control
regulator.
