Verify that the signal cable connecting the Y-axis driver to the camera is connected correctly.
After connecting the signal cable, measure the voltages at terminals A+/A- and B+/B- to ensure they are within the normal range.
Confirm that the motor version is compatible with the pin configuration of the signal cable connection.
Adjust the pin connection method to match the specific version of the current driver (refer to the driver’s instruction manual).
Verify that the current pin outputs are functioning correctly.
Attempt an alternative wiring configuration.
