Set Values<br />
Set<br />
Description<br />
value<br />
0 No PID control.<br />
1 PID control with deviation differential control.<br />
2 PID control with feedback differential control.<br />
Note Set n084 to 1 or 2 to permit the Inverter to perform PID control. Usually n084 is set to 2.<br />
• If n084 is set to 1 or 2, the method to input the set point will be determined<br />
by the operation mode set with n002 and the FI terminal will be<br />
used for feedback input. Set the FI input level with n043 to select current<br />
feedback input or voltage feedback input to the Inverter.<br />
