5.11 Group 10: PID Control Parameters

10 - 00 Input Terminal for PID Feedback

Settings	00: No function
	01: Input via AVI
	02: Input via ACI1
	03: Input via ACI2
	04: Input via External Reference

This parameter is to set the source of PID control feedback signal. The source could be AVI, ACI1, ACI2 or external reference that defined by 04-24.

When this parameter is set to 00, PID feedback control function is disabled.

When this parameter is set to 02/03 and analog input current of ACI1/ACI2 is lower than Pr.04-13/Pr.04-17, EF warning will pup-up.

If this parameter isn’t set to 00, AC drive will automatically start-up PID feedback control. Output frequency is calculated by master frequency and PID feedback signal.

10 - 01	PID Control Detection Signal Reference		Factory Setting: 1000.0
	Settings	0.0-6550.0	Unit: 0.1
Please refer to 04-09 to 04-20 if this parameter is set to PID feedback control.
10 - 02	PID Feedback Control Method		Factory Setting: 00
	Settings	00: Negative feedback control
		01: Positive feedback control

This parameter could set the calculation method of deviation signal during PID feedback control circuit.

When this parameter is set to 00: when negative feedback control, the deviation equation is deviation = target value – detection signal. When increasing output frequency will increase detection value, this setting should be chose.
