If Auto-Tuning cannot be performed for some reason (no-load operation impossible, etc.), then set the maximum
frequency and voltage in the E1- parameters and enter the motor data manually into the E2- parameters. Refer to
Auto-Tuning Errors on page 41.
Precautions
• Rotational Auto-Tuning T1-01 = 0 (recommended method)
• Rotational Auto-Tuning provides more accurate tuning results compared to Non-Rotating Auto-Tuning.
• Perform Rotational Auto-Tuning when the pump can be set to bypass mode (remove ropes from traction sheave).
• Stationary Auto-Tuning T1-01 = 1, 2, or 4 (alternate method)
• Perform Stationary Auto-Tuning when the motor and mechanical system cannot be uncoupled.
• Make sure that the mechanical brake remains applied for all Stationary Auto-Tuning methods.
• When using a motor contactor, make sure it remains closed during the Auto-Tuning process.
• Ensure H1 and H2 signals are ON when performing Auto-Tuning.
• Ensure the motor is securely mounted and bolted in place prior to Auto-Tuning.
• Do not touch the motor until the Auto-Tuning process is complete. Voltage is applied to the motor during the tuning
process, even though the motor may not be rotating.
• To cancel Auto-Tuning, press the STOP key on the digital operator.
• During Auto-Tuning the motor is started and stopped repeatedly and may also rotate. When the tuning is finished,
“END” will appear on the operator panel. Do not touch the motor until this display is shown and the motor has
completely stopped.
