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 for motor data or PG encoder offset, 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. Use parameter S1-12 to enable/disable automatic switching of the Motor Contactor Control
output signal during Auto-Tuning. When using setting S1-12 = 1 or 2, ensure that the multi-function output terminals are properly wired
and in the correct state before setting parameter S1-12. Failure to comply could result in damage to the drive, serious injury or death.
WARNING! Sudden Movement Hazard. If installed, 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.
Note: 1. 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 motor can be uncoupled from the elevator mechanical system (remove ropes from
traction sheave).
 Make sure to release the mechanical brake (if installed) for Rotational Auto-Tuning methods.
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.
2. When using a motor contactor, make sure it remains closed during the Auto-Tuning process.
3. Ensure H1 and H2 signals are ON when performing Auto-Tuning.
4. A digital input programmed for Baseblock (H1- = 8/9) must be set so that the drive is not in a baseblock condition during
Auto-Tuning.
5. Ensure the motor is securely mounted and bolted in place prior to Auto-Tuning.
6. To cancel Auto-Tuning, press the STOP key on the digital operator.
7. Make sure motor nameplate data is readily available before Auto-Tuning the drive. Auto-Tuning requires the user to input data from
the motor nameplate or motor test report.
8. When performing Auto-Tuning for motor 2, make sure motor 2 is connected to the drive output terminals.
9. For best performance, the drive input power supply voltage should be greater than the motor rated voltage.
10. Improved performance is possible when using a motor with a base voltage that is 10% less than the input supply voltage. This is
particularly important when operating the motor above 90% of base speed, where high torque precision is required.
WARNING! Sudden Movement Hazard. System may start unexpectedly upon application of power, resulting 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.
