D-87
AC30V series Variable Speed Drive
PNO Parameter Descriptions
Speed Loop Int Defeat
When TRUE, the integral term does not operate.
Speed Loop Int Preset
The integral term will be preset to this value when the drive starts.
Spd Loop Dmd Filt TC
The speed demand is filtered to reduce ripple. The filter is first order with time constant equal to the value of this parameter.
Spd Loop Fbk Filt TC
The speed feedback is filtered to reduce ripple. The filter is first order with time constant equal to the value of this parameter.
Spd Loop Aux Torq Dmd
When the drive is operating in speed control mode, the value of this parameter is added on to the torque demand produced by the
speed loop PI. When the drive is operating in torque control mode (i.e.
Set Torq Ctrl Only
is TRUE) the speed loop PI does not
operate, and the torque demand becomes the sum of this parameter plus the DIRECT INPUT (if selected).
Spd Loop Adapt Thres
If the speed demand is less than the
Spd Loop Adapt Thres
, the speed loop proportional gain is the
Spd Loop Adapt Pgain
.
Spd Loop Adapt Pgain
Proportional gain used if speed demand <
Spd Loop Adapt Thres
.
Spd Demand Pos Lim
This sets the upper limit of the speed demand.
Spd Demand Neg Lim
This sets the lower limit of the speed demand.
Sel Torq Ctrl Only
Selects between Speed Control mode and Torque Control mode. When TRUE, (Torque Control mode) the torque demand output
from the speed loop feature is the sum of the Direct Input plus the
Spd Loop Torq Dem
parameter.
Functional Description
The speed error (speed demand minus speed feedback) is calculated and processed via a propor integral (PI) controller. The output of
the PI controller is a torque demand, which is passed directly to the torque control feature.
When the drive is in SENSORLESS VEC mode, the speed feedback is calculated from the voltages and currents flowing in the motor, and the
motor model.
