PID output

characteristic

0~1 【 0 】

0 ： Positive. When the feedback value is greater

than the preset value, output frequency will be

decreased, such as tension control in winding

application.

1: Negative. When the feedback value is greater

than the preset value, output frequency will be

increased, such as tension control in unwinding

application.

control:

Use the following procedure to activate PID

control and then adjust it while monitoring the

response.

1. Enabled PID control ( F0 .0 7 =6)

2. Increase the proportional gain (Kp) as far as

possible without creating oscillation.

3. Reduce the integral time (Ti) as far as

possible without creating oscillation.

4. Increase the differential time (Td) as far as

possible without creating oscillation.
