7.3 Instance 102, Grey Output Channel 1 (adjustment function)
Danger of physical injury and material damage due to an actual value
jump during execution of the adjustment function!

The adjustment function should only be executed when the measuring
system is stationary, or the resulting actual value jump must be
permitted by both the program and the application!
A 32-bit adjustment value can be transferred and set as a new position value in Instance 1 and
Instance 101 (Position Value Unsigned) via Instance 102, Member TR Grey – Preset
Control (Control word) and Member Preset Value (Adjustment value). The adjustment value
must be within the programmed measuring range –1. An invalid adjustment value transmitted is not
accepted and error code 0x0080 is indicated in the status word TR Grey – Encoder Status.
Control word = 0x0000 deletes the error code in the status word TR Grey – Encoder Status.
The adjustment value is set with a rising edge 0->1 of bit 2
0
(0x0001) in the control word. Execution of
the adjustment is acknowledged in the status word TR Grey – Encoder Status by setting bit 2
0
(0x0001). Cancelling bit 2
0
(0x0000) in the control word automatically resets bit 2
0
(0x0000) in the
status word TR Grey – Encoder Status.
