PID Offset Level Settings To 50.0 % | Delta Electronics VFD-M

Pr. 125

			Chapter 4 Parameters
	Pr. 122	PID Frequency Output Command limit
		Settings 00 to 110 %	Factory Setting: 100

This parameter sets a limit of the PID Command frequency. If this parameter is set to 20%, then the maximum output frequency for the PID operation will be (20% x Pr.03).

Pr. 123	Feedback Signal Detection Time	Unit: 0.1sec
		Factory Setting: 60.0

Settings 0.1 to 3600 sec 0.0 disable

This parameter defines the detection time for the loss of a feedback analog signal. The drive will follow the operating procedure programmed in Pr.124 if the feedback signal is lost for more than the time set in Pr.123.

Pr. 124 Feedback Signal Fault Treatment

Factory Setting: 00

Settings 00 Warning and RAMP to stop 01 Warning and keep operating

This parameter selects the operation of the drive upon a loss of the PID feedback signal.

Source of PID Set point

		Settings	0.00 to 400.0Hz	Factory Setting: 0.00
	This parameter is used in conjunction with Pr.115 (04) to input a set point in Hz.

	Pr. 126	PID Offset Level
		Settings	1.0 to 50.0 %	Factory Setting: 10.0

	This parameter is used to set the offset between set point and feedback.

	Pr. 127	Detection Time of PID Offset
		Settings	0.1 to 300.0 sec	Factory Setting: 5.0

	This parameter is used to set the detection time of PID offset.

	Pr. 128	Minimum Reference Value		Unit: 0.1V
		Settings	0.0 to 10.0 V	Factory Setting: 0.0

This parameter is used to set the AVI input voltage that corresponds to minimum frequency.
