6.8 Group 6 – PID setup
To regulate the motor speed related to a process value the inverter has a PID controller integrated. This is a
closed loop control.
Example:
Using an feedback signal (i.e. pressure transducer) the inverter can regulate the speed.
Setup procedure:
1. Select the correct PID Operating mode (P600:1)
2. Select the PID feedback source (P600:2) and setup the analog input accordingly
3. Select the PID default setpoint source (P201:2)
4. Set the PID speed range (P600:3) to a proper value
5. Test and tune your PID control
(Start with default settings first)
6. Set additional functions (if needed)
Setpoint ramp time, PID ramp time, Min/Max Alarm, line speed, influence function.
