9-3
Commonly used PID control modes
1:
Forward operation: PID operation enabled, motor speeds increases when feedback signal is smaller than
set-point (most fan and pump applications)
3:
Reverse operation: PID operation enabled, motor slows down when feedback signal is smaller than set-point
(e.g. level control applications)
To set parameter 10-03:
- After power-up press the
MODE
key
- Select 10-03 using the arrow keys and up/down keys
- Press
</ENTER
key
- Set parameter 10-03 using the arrow keys and
</ENTER
key to save setting.
9.2 Connect Transducer Feedback Signal (10-01)
The PID function in the inverter
Depending on the type of feedback transducer used, the inverter can be setup for either 0-10V or a 4-20mA
feedback transducer.
