Ki speed offset accel.
Ki speed offset decel.
The proportional gain of the speed controller is split into two values,
one for acceleration and constant run and one for deceleration. This
provides the greatest degree of flexibility. The default values are set
the same for both and will work for most applications. However if the
motor does not track the speed command tight enough, then the value
should be increased. If the motor makes audible noise or vibration
in the car, then the gain value should be reduced. Adjustment steps
of +/- 250 are reasonable.
Unit: 1
Value range: 1...32767
Factory setting : 3000 Accel. , 3000 Decel.
The integral gain of the speed controller is split into two values, one for
acceleration and constant run and one for deceleration. The default
values are a good staring point and will work for most applications.
Higher integral values can lead to jerks in the acceleration or
deceleration.
Unit: 1
Value range: 1...32767
Default setting: 350 Accel. , 250 Decel.
This gain value is effective only at low speeds. This value is added to
the I term gain in LF.32 to provide greater control and more stability.
This offset acceleration gain will assist the motor in catching the load
during starting. It is especially important for high efficiency geared or
gearless applications. Values of 2,000 to 5,000 are useful.
The offset deceleration gain will allow the system track the command
speed tightly at low speed. Often lower values are required than for
starting. Values of 500 to 2,000 are useful.
Unit: 1
Value range: 0...8000
Default setting: 3000 Accel. , 1000 Decel.
The offset gain value is tapered off beginning at about 8 ft/min and the
offset reaches zero at 24ft/min. The corner speeds can be adjusted
through parameters US.20 and US.21.
