VFD-F Series

When this parameter is set to 01: when positive control, the deviation equation is deviation

=detection signal – target value. When increasing output frequency will decrease detection value, this setting should be chose.

10 - 03 Proportional Gain (P)

Settings 0.0~10.0Unit: 0.1 This parameter is to set proportional gain (P). This gain determines the response degree of P controller to feedback deviation. If gain value is large, the response is fast. But if the gain value is too great, oscillation will occur. If gain value is small, the response is slow.

10 - 04 Integral Time (I)

Settings 0.00~100.00 SecUnit: 0.01 This parameter is set to integral gain of I controller. When much integral time is to be set, the gain of I controller is small and the response is slow. The control ability to external is poor. When less integral time is to be set, the gain of I controller is large and the response is fast. The control ability to external is fast.

If the setting of integral time is too small, output frequency and system may occur oscillation.

If integral time is set to 0.00, I controller is closed.

10 - 05 Differential Time (D)

Settings 0.00~1.00 SecUnit: 0.01 This parameter is set to D controller gain. This gain determines D controller to the response of change of deviation. Suitable differential time could decrease overshoot of P and I controller. The oscillation will be attenuation and steady quickly. But if much differential time is to be set, it may cause system oscillation.

Interference immunity ability is poor due to differential controller activates to change of deviation. It’s not recommended to use, especially during interferences.

10 - 06	Upper Bound for Integral Control		Factory Setting: 100
	Settings	00~200%	Unit: 1

This parameter could set the upper bound of I controller. In other words, upper bound for integral control = (01-00) X (10-04) %

10 - 07	Primary Low Pass Filter Time		Factory Setting: 0.0
	Settings	0.0~2.5 Sec	Unit: 0.1
This parameter determines primary Low Pass filter time.
