0x2804 Freeze object
This object is used to configure the freeze function that can be used within the Homing
mode profile. Table 7.55 Freeze object on page 53 specifies the object description.
Table 7.55 Freeze object
0x607C Home offset
This object indicates the configured difference between the zero position for the
application and the machine home position (found during homing). During homing the
machine home position is found and once the homing is completed the zero position is
offset from the home position by adding the home offset to the home position. All
subsequent absolute moves shall be taken relative to this new zero position. This is
illustrated in Figure 7-11 Home offset definition on page 53. The value of this object
shall be given in user-defined position units. Negative values indicate the opposite
direction.
