How To Stop The Procedure 'Self-Tune'; What Happens If A Fault Occurs During 'Self-Tune'?; Start 'Self-Tune' - Reliance electric GV3000/SE Instruction Manual

WARNING: The subsequent steps require rotating parts and/or electrical circuits
exposed. Stay clear and disconnect and lockout or tag power source when contact
must be made. Failure to observe this precaution could result in bodily injury or
loss of life.
1. Switch line voltage on.
2. Check that important parameter values are correct before initiating 'Self-Tuning':
• U.002 Motor Poles
• U.003 Motor Namepl. Base Frequency
• U.004 Motor Nameplate Amps
• U.007 Motor Nameplate Volts
•
U.016 Field Weakening Speed in RPM (If field weakening is used)
• U.017 Motor Top Speed in RPM
3. Verify that the motor is unloaded (to enable controller to calculate correctly no load current, U.006).
4. The controller must not be running. Press the STOP/RESET key.
5. Clear the error log of all errors. (Refer to "View Fault Codes, Clear the Error Log", in Section 3.)
6. Set P.000 = 0 for Local operation, or =1 for Remote operation.

How to Stop the Procedure 'Self-Tune'

- When 'Self-Tune' is enabled (U. 008 is turned ON) but not active, set U.008 to OFF.
- If Self-Tune is STARTED (display shows S_Ac), press the STOP/RESET key or activate 'FUNCTION
LOSS'.

What happens if a Fault occurs during 'Self-Tune'?

1. If a stop is commanded and Self-Tune is aborted, the drive will shut off, and coast to stop. An error
message (SF) is displayed.
2. Once Self-Tune is stopped, parameter U.008 will be updated to OFF, and the drive is taken out of the
Self-Tune mode.

Start 'Self-Tune'

1. Enable the Self-Tune parameter. Set U.008 = ON.
2. Exit the PROGRAM mode and enter the MONITOR mode. (Press the PROGRAM key twice when in
the parameter list. The display should show S_En when the PROGRAM mode is exited, and the
monitor mode is entered.)
WARNING: The user is responsible to ensure that driven machinery, all drive-train
parts, and process line material are capable of safe operation at maximum operating
speed. Overspeed detection in the drive determines when the drive shuts down and is
factory set at Vector Mode to 130% of Maximum Speed (RPM). Failure to observe this
precaution could result in bodily injury.
ATTENTION: The motor will rotate during the Self-Tune procedure. The motor must
be uncoupled from the driven load during the self-tuning operation or incorrect
parameter values will result. This includes any shaft-coupled devices, such as
reducers, belts, and brakes. Failure to observe this precaution could result in damage
to, or destruction of, the equipment.
3. Press the START key on the keypad. The display will show S_Ac when Self-Tune is active.
The controller will ramp up to value U.017 Motor Top Speed, and perform Self-Tune calculations.
Important: If Self-Tune aborts, and "SF" is displayed during Self-Tune, refer to Section 7 for a complete
action chart for troubleshooting.
