Relative offset limits

Definition

After HB is selected, offset limits act relative to the current axis position (start position) and are defined by:

• P-AXIS-00137 and P-AXIS-00138 or
• #MANUAL LIMITS[...]

Activate the monitor

To activate the relative offset limit monitor, at least one of the limits P-AXIS-00137 or P-AXIS-00138 must be configured with the value ≠ 0.

Notice

If both limits = 0, the monitor is not active.

Warnings, errors and reactions

• Warning P-ERR-50720: When the monitor is active, the relative offset limits are reached. The warning is output only if P-MANU-00014 is configured accordingly.

• Warning P-ERR-150008: When the monitor is active, the relative offset limits are exceeded in jog mode by additional command values.

• Error message P-ERR-50041 or P-ERR-50042: With G201, software limits switches are exceeded.

Modulo axis

For modulo axes, relative offset limits can include several modulo revolutions. The specified relative offset limits refer to the axis position that was valid when it was activated by G200 or G201.

This reference position can by determined by the CNC object with (index group 0x21301 and index offset 0x2000C) or directly on the HLI.

For example, the second axis in the first channel can be read via the GEO port with index group 0x21301 and offset 0x20007.

Change reference position

If the reference position is changed, a path motion and re-activation of the manual mode axis are required.
