Function
Set acceptable limits for the references.
3 3
Check that the ramp settings are within adjustable
frequency drive capabilities and the allowed application
operating specifications.
Set acceptable limits for the motor speed and frequency. 4-11 Motor Speed
4) Configure the Speed Control and select the Motor Control principle
Activation of Speed Control.
Selection of Motor Control Principle.
5) Configure and scale the reference to the Speed Control
Set up Analog Input 53 as a reference source.
Scale Analog Input 53 0 RPM (0 V) to 1500 RPM (10 V).
6) Configure the 24 V HTL encoder signal as feedback for the Motor Control and the Speed Control
Set up digital input 32 and 33 as HTL encoder inputs.
Select terminal 32/33 as motor feedback.
Select terminal 32/33 as Speed PID feedback.
7) Tune the Speed Control PID parameters
Use the tuning guidelines when relevant or tune
manually.
8) Save to finish
Save the parameter setting to the LCP for safe keeping.
