Additive offsets

Zero offsets external
The "zero offset external" is an axial offset. Unlike with frames, no components for rotation, scaling and mirroring
are possible.
Figure 10-16 Zero offset external between BCS and BZS
Setting the offset values
The offset values are set:
• PLC
By describing system variables
• Via the operator panel
From menu "Current zero offsets"
• NC Program
By assigning to system variable $AA_ETRANS[axis]
Activation of the offset values
The 0/1 edge of the following PLC signal activates the previously defined offset values:
DB31, ... DBX3.0 (accept external zero offset)
The 0/1 edge change is only evaluated in Automatic operating mode.
