AC890PX AC Drive
Parameter Descriptions
INT DEFEAT
PREF: 78.03
Default: FALSE
Range: FALSE / TRUE
When TRUE, the integral term does not operate.
SPEED INT PRESET
PREF: 78.04
Default: 0.00 %
Range: -500.00 to 500.00 %
The integral term will be preset to this value when the drive starts.
SPEED DMD FILTER
PREF: 78.05
Default: 0.0 ms
Range: 0.0 to 14.0 ms
The speed demand is filtered to reduce ripple. The filter is first order with time constant equal to the value of this parameter.
SPEED FBK FILTER
PREF: 78.06
Default: 0.0 ms
Range: 0.0 to 15.0 ms
The speed feedback is filtered to reduce ripple, such as that caused by low line count encoders. The filter is first order with
time constant equal to the value of this parameter.
AUX TORQUE DMD
PREF: 78.07
Default: 0.00 %
Range: -300.00 to 300.00 %
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. “torque demand isolate 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).
ADAPTIVE THRESH
PREF: 78.08
Default: 5.00 %
Range: 0.00 to 10.00 %
If the speed demand is less than the adaptive threshold, the speed loop proportional gain is the adaptive p-gain.
ADAPTIVE P-GAIN
PREF: 78.09
Default: 20.00
Range: 0.00 to 300.00
Proportional gain used if speed demand < adaptive threshold.
