Basic Auto-Tuning Preparations and Precautions
WARNING! Sudden Movement Hazard. When performing Rotational Auto-Tuning for motor data or PG encoder offset, always
uncouple the motor from the mechanical system (remove ropes from traction sheave). Performing Rotational Auto-Tuning with the
mechanical system connected to the motor can cause hazardous situations, injury to personnel and damage to the equipment.
WARNING! Electrical Shock Hazard. Do not touch the motor during Auto-Tuning. Lethal voltages may be present on the motor case.
Failure to comply may result in serious injury from electrical shock.
WARNING! Electrical Shock Hazard. When executing Stationary Auto-Tuning, the motor does not rotate, however, power is applied.
Do not touch the motor until Auto-Tuning is completed. Failure to comply may result in death or serious injury from electrical shock.
WARNING! Sudden Movement Hazard. The holding brake must remain engaged for the entire Stationary Auto-Tuning sequence.
Ensure a brake release digital output signal cannot be issued by the drive. Failure to comply could result in serious injury or death.
WARNING! Sudden Movement Hazard. Do not release the mechanical brake during Stationary Auto-Tuning. Inadvertent brake
release may cause damage to equipment or injury to personnel. Ensure that the mechanical brake release circuit is not controlled by
the drive multi-function digital outputs exclusively.
• Rotational Auto-Tuning is the preferred tuning method because it gives more accurate results than Stationary Auto-
Tuning. Perform Rotational Auto-Tuning when the motor can be uncoupled from the elevator mechanical system
(remove ropes from traction sheave). 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. Make sure to release the
brake for all Rotational Auto-Tuning methods.
• When using a motor contactor, make sure it is closed throughout the Auto-Tuning process.
• The H1 signal must be ON when performing Auto-Tuning.
• A digital input programmed for Baseblock (H1-
• Confirm that the motor is mechanically fixed.
• To cancel Auto-Tuning, press the STOP key on the digital operator.
• Auto-Tuning requires the user to input data from the motor nameplate or motor test report. Make sure this data is
available before Auto-Tuning the drive.
• For best performance, the drive input supply voltage must be greater than the motor rated voltage.
Note: Improved performance is possible when using a motor with a base voltage that is 20 V (40 V for 400 V class models) lower than
the input supply voltage. This is particularly important when operating the motor above 90% of base speed, where high torque
precision is required.
DANGER! Sudden Movement Hazard. Stay clear of the motor during rotational autotuning. The motor may start operating suddenly.
During automatic starting of equipment, the machine may start moving suddenly, which could result in death or serious injury.
• Clear all personnel from the drive, motor, and machine area before applying power.
• Secure covers, couplings, shaft keys, and machine loads before applying power to the drive.

u Auto-Tuning Interruption and Fault Codes
If tuning results are abnormal or the STOP key is pressed before completion, Auto-Tuning will be interrupted and a fault
code will appear on the LED operator.
