If you are using a Hall sensor, you do not need to set this parameter.

If you are not using a Hall sensor (PM.003.Y = 0), the servo automatically detects the motor magnetic

field when the servo is on for the first time after powering on. Use this parameter to set the current during

the motor magnetic field detection. The current affects the swaying level of the linear motor during

detection, and the servo obtains the magnetic field data through the swaying. Adjust this parameter when

the following condition occurs:

When the friction between the motor and the mechanism is too large, magnetic field detection error

may occur which triggers AL052. Increase the set value of this parameter can reduce the

occurrence of AL052.

When the linear motor sways too much, lower the set value of this parameter to reduce the swaying

during magnetic field detection.

Initial magnetic field current detection cannot be applied to Z axis without the spring installed or balancing process.

Without the spring or balancing process, the Z axis has different frictional forces in the up and down direction, which

will affect the result of the magnetic field detection. In this case, you can only add a Hall sensor.

The gantry application requires a Hall sensor for initial magnetic field detection.
