To Perform With-Load Auto-Tuning For Asynchronous Motor - Monarch NICE3000 User Manual

Use of the NICE3000
To perform with-load auto-tuning for asynchronous motor, do as follows:
1) Set F0-01 (Command source selection) to 0 (Operation panel control) and press
STOP
on the operation panel to reset the current faults.

2) Enter the motor nameplate parameters correctly.
• F1-01 (Rated motor power)
• F1-02 (Rated motor voltage)
• F1-03 (Rated motor current)
• F1-04 (Rated motor frequency)
• F1-05 (Rated motor rotational speed)
Set F1-12 (Encoder lines per revolution) based on the encoder nameplate.
3) Set F1-11 to 1 (With-load auto-tuning) if the load cannot be removed from the motor
completely. Then "TUNE" is displayed on the operation panel. Press
the operation panel. The controller starts motor auto-tuning, measures the stator
resistance, rotor resistance and leakage inductance successively and automatically
calculates the motor's mutual inductance and no-load current. After the auto-tuning is
complete, the running contactor opens.
4) Run the motor at the inspection speed and check:
• Whether the running current is normal
• Whether the actual running direction of the elevator is consistent with the given
direction
• Whether the pulse direction is correct
Ensure that F4-03 (Low byte of current floor position) increases when you press the UP
key and decreases when you press the DOWN key.
The elevator running direction and pulse direction can be modified by F2-10 (Elevator
running direction).

• Ensure that the UVW power cables of the motor are connected to the UVW terminals of the
controller properly.
• Ensure that the AB, CDZ signal wires of the ERN1387 SIN/COS encoder are connected to the
AB, CDZ terminals of the PG card properly. The AB, UVW signal cables of the UVW encoder
are connected to the AB, UVW terminals of the PG card properly.
• Make sure that F8-01 (Pre-torque selection) is set to 0 (Pre-torque invalid). Otherwise, the
elevator runaway may result during the auto-tuning.
• If the auto-tuning still fails (the motor does not run or suddenly runs in one direction and then
stops) when the UVW power cables of the motor are correctly wired, exchange any two output
power cables of the controller and perform the motor auto-tuning again.
• Ensure that there is nobody in the shaft because the auto-tuning process is dangerous.
