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

4.5 Auto-Tuning
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.
