165

Tune Test Status

Indicates which test (if any) is in progress.
• Value 7 is retained and is used to continue the Auto Tune test from the last point at which it was stopped.
Notes: Value 5 was changed to “Reserved” for firmware version 2.004. Value 7 “Mtr+Sys J” was changed to “Slip
Test” for firmware version 3.001. Value 8 “Find Home” was added for firmware version 3.003.

166 Motor

Ctrl

Cmmd

Displays the command bits to the Motor Control Processor from the Velocity Processor.

167 Motor

Ctrl

Ackn

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

168

Normal Stop Mode

Sets the method of stopping the drive when a stop command is given. Normal Stop command and the RUN input
changing from true to false will command a Normal Stop.

Ramp Stop = decelerates to zero speed at the decal rate
CurLim Stop = Max torque / current applied until zero speed
Coast Stop = power removed from motor, motor coasts to zero

169

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.
• Turn-on level for rising feedback = 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).

Setpt 1 Limit

Creates a tolerance - hysteresis band around the value in

Par 173

[Setpt1 TripPoint].

• Turn-on level for ascending data = TripPoint - Limit.
• Turn-off level for ascending data = TripPoint + 2(Limit).
• Turn-on level for descending data = TripPoint + Limit.
• Turn-off level for descending data = TripPoint - 2(Limit).
