3.3 Machine Rotary Zero Point (MRZP) Offsets
The Machine Rotary Zero Point (MRZP) Offsets are control settings that define the location
of the centers of rotation for the rotary table relative to the linear axes home position.
Settings 255, 256, and 257 define the following:
255 – MRZP X Offset
Location of the B Axis rotary center point relative to the X Axis home position.
256 – MRZP Y Offset
Location of the C Axis rotary center point relative to the Y Axis home position.
257 – MRZP Z Offset
Location of the B Axis rotary center point relative to the Z Axis home position.
The value stored in these settings is the distance from the home position of a linear axis to
the center of rotation of a rotary axis. Setting 9 determines if the values are shown in inches
or millimeters.
The Machine Rotary Zero Point (MRZP) Offsets are set at the factory.
3.3.1 Check MRZP Offsets with VPS
The MRZP offsets can change over time. To make sure the UMC-1000, MRZP Offsets
are correct do the following:
1.
Place the tooling ball in the center of the X axis.
IMPORTANT: Make sure that the tooling ball is tightly attached to the calibration
assembly. Do not over tighten the tooling ball.
