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 Parameter Setting
1) Make sure the motor runs properly. Do the following:
Set the motor parameters using name plate data 1-2* As specified by motor name plate
Have the frequency converter makes an Automatic Motor
Adaptation
1-29 Automatic Motor
Adaptation (AMA)
[1] Enable complete AMA
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”).
Set a positive reference.
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.
16-20 Motor Angle N.A. (read-only parameter) Note: An increasing
value overflows at 65535 and starts again at 0.
If 16-20 Motor Angle is decreasing then change the encoder
direction in 5-71 Term 32/33 Encoder Direction.
5-71 Term 32/33
Encoder Direction
[1] Counter clockwise (if 16-20 Motor Angle is
decreasing)
3) Make sure the frequency converter limits are set to safe values
Set acceptable limits for the references. 3-02 Minimum
Reference
3-03 Maximum
Reference
0 RPM (default)
1500 RPM (default)
Check that the ramp settings are within frequency converter
capabilities and allowed application operating specifications.
3-41 Ramp 1 Ramp Up
Time
3-42 Ramp 1 Ramp
Down Time
default setting
default setting
Set acceptable limits for the motor speed and frequency. 4-11 Motor Speed Low
Limit [RPM]
4-13 Motor Speed High
Limit [RPM]
4-19 Max Output
Frequency
0 RPM (default)
1500 RPM (default)
60 Hz (default 132 Hz)
4) Configure the Speed Control and select the Motor Control principle
Activation of Speed Control
1-00 Configuration
Mode
[1] Speed closed loop
Selection of Motor Control Principle 1-01 Motor Control
Principle
[3] Flux w motor feedb
5) Configure and scale the reference to the Speed Control
Set up Analog Input 53 as a reference Source 3-15 Reference
Resource 1
Not necessary (default)
Scale Analog Input 53 0 RPM (0V) to 1500 RPM (10V) 6-1* Not necessary (default)
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 5-14 Terminal 32
Digital Input
5-15 Terminal 33
Digital Input
[0] No operation (default)
Choose terminal 32/33 as motor feedback 1-02 Flux Motor
Feedback Source
Not necessary (default)
Choose terminal 32/33 as Speed PID feedback 7-00 Speed PID
Feedback Source
Not necessary (default)
7) Tune the Speed Control PID parameters
Use the tuning guidelines when relevant or tune manually 7-0* See the guidelines below
8) Finished!
