7.3.2 Testing Encoder Rotation

Context:
Use this procedure if encoder feedback is used. For more information on the encoder option, refer to the option manual.
Procedure
1. Select [0] Open Loop in parameter 1-00 Configuration Mode.
2. Select [1] 24 V encoder in parameter 7-00 Speed PID Feedback Source.
3. Press [Hand On].
4. Press [►] for positive speed reference (parameter 1-06 Clockwise Direction at [0] Normal).
5. Check feedback in parameter 16-57 Feedback [RPM].
- If feedback is positive, the test was successful.
- If feedback is negative, the encoder connection is wrong. Use either parameter 5-71 Term 32/33 Encoder Direction or parameter
17-60 Feedback Direction to inverse the direction, or reverse the encoder cables. Parameter 17-60 Feedback Direction is only available
with the VLT® Encoder Input MCB 102 option.

7.4 Starting Up the Drive for the First Time

Context:
The procedure in this section requires user-wiring and application programming to be completed. The following procedure is
recommended after application set-up is completed.
MOTOR START
Starting the drive can cause the motor to start. Failure to ensure that the motor, system, and any attached equipment are ready
for start can result in personal injury or equipment damage.
Ensure that equipment is safe to operate under any condition.
-
Ensure that the motor, system, and any attached equipment are ready for start.
-
1. Press [Auto On].
If warnings or alarms occur, see the Warnings and Alarms section.
2. Apply an external run command. Examples of external run commands are a switch, button, or programmable logic controller (PLC).
3. Adjust the speed reference throughout the speed range.
4. Ensure that the system is working as intended by checking the sound and vibration levels of the motor.
5. Remove the external run command.

7.5 Parameter Settings

7.5.1 Parameter Setting Overview

Parameters are operational settings accessed through the LCP that are used to configure and operate the drive and motor for specific
applications.
