5.11 Group 10: PID Control Parameters

10 - 00

Input Terminal for PID Feedback

Settings
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.

PID Control Detection Signal Reference

Settings
Please refer to 04-09 to 04-20 if this parameter is set to PID feedback control.

PID Feedback Control Method

Settings
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.
