The Siemens servo motor, model 1FT603-1FT613, has a damaged built-in encoder. The incremental encoder it is equipped with is an ERN1387.001/020 from Heidenhain, Germany . How can it be installed and debugged on-site?
A: For Siemens servo motor 1FT603-1FT613, reinstalling the built-in incremental encoder (ERN1387.001/020 ) requires adjusting the encoder position. This is to ensure that the motor's stator magnetic field is orthogonal to the rotating magnetic field of the three-phase AC power supply, thus achieving vector control of the motor by the servo unit. Otherwise, the motor will not rotate or may run away. When installing the encoder, pay attention to its installation direction; align the markings on the motor shaft with the markings on the encoder.
Please note that when adjusting the built-in incremental encoder of the vertical axis servo motor, it is best to disengage the motor from the coupling, place it in a horizontal position, and adjust the encoder with the power off. After adjustment, power on and test. Under normal circumstances, with the Z-axis enabled but without pressing the 'JOG' key, the Z-axis motor should be stationary. Pressing the 'JOG' key (jog key) will cause the Z-axis motor to rotate normally, indicating that the built-in incremental encoder is correctly adjusted. Otherwise, if the Z-axis motor runs wildly when enabled but without pressing the 'JOG' key, the built-in incremental encoder adjustment is incorrect and must be repeated. It is crucial to ensure that the motor is disengaged from the coupling, placed in a horizontal position, and the power is off when adjusting the built-in incremental encoder. Otherwise, the machine tool may be damaged.
