Introduction
The following must be programmed in order shown (see explanation of settings in the Programming Guide)
In Table 3.6 it is assumed that all other parameters and switches remain at their default setting.
Function
1) Make sure the motor runs properly. Do the following:
Set the motor parameters using name plate data
3 3
Have the frequency converter makes an Automatic Motor
Adaptation
2) Check the motor is running and the encoder is attached properly. Do the following:
Press the "Hand On" LCP key. Check that the motor is
running and note in which direction it is turning (henceforth
referred to as the "positive direction").
Go to 16-20 Motor Angle. Turn the motor slowly in the
positive direction. It must be turned so slowly (only a few
RPM) that it can be determined if the value in 16-20 Motor
Angle is increasing or decreasing.
If 16-20 Motor Angle is decreasing then change the encoder
direction in 5-71 Term 32/33 Encoder Direction.
3) Make sure the frequency converter limits are set to safe values
Set acceptable limits for the references.
Check that the ramp settings are within frequency converter
capabilities and allowed application operating specifications.
Set acceptable limits for the motor speed and frequency.
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 (0V) to 1500 RPM (10V)
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 encoder inputs
Choose terminal 32/33 as motor feedback
Choose terminal 32/33 as Speed PID feedback
7) Tune the Speed Control PID parameters
Use the tuning guidelines when relevant or tune manually
8) Finished!
