9-3
Commonly used PID control modes
0001b:
Forward operation: PID operation enabled, motor speeds increases when feedback signal is
smaller than set-point (most fan and pump applications)
0011b:
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
DSP/FUN
key
- Select
10 PID Control
- Press
READ/ ENTER
key
- Select parameter -03
with the
UP/DOWN
▲ and ▼ keys and press the
READ/ ENTER
key.
Important:
To use the PID function parameter 00-05 (Main Frequency Command Source Selection)
has to be set to 5 for PID reference.
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.
