Auto-Tuning Interruption And Fault Codes - YASKAWA L1000A Technical Manual

• 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.
• When using Auto-Tuning for motor 2, make sure motor 2 is connected to the drive output when performing the tuning.
• 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.
Table 4.10 describes digital input and output terminal operation while Auto-Tuning is executed.

Note: When using a PM motor for the first time or when replacing the drive or PM motor, be sure to set the motor parameters properly
and check that the speed detection functions properly prior to operation. Using a PM motor requires setting the encoder offset
correctly and entering motor data. Perform Encoder Offset Auto-Tuning after replacing the motor, encoder, or drive. Insufficient
torque may cause the elevator car to move in the direction of the load or cause the motor to behave erratically (reverse operation,
stand still, sudden accelerations, etc.). For more information, refer to the instruction manual included with the motor.

◆ 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 digital operator.
