4.8
The offset value is added to the target angle. This is an absolute position value and it is
also set regardless of the number of communication transmissions and always as an ab-
solute offset value for the target angle. This means that if, for example, the same offset
value is set twice through communication the value will not be added twice.
If the offset is not 0, then

deviate from each other by the offset value. When the offset is reset to 0, the output angle
set value will correspond with the target angle.
The format of the parameter is 32 Bit angle. However, in contrast to Parameter

136.7
Offset speed
The parameter acts as offset speed when the position control is active with cyclical syn-
chronous position set value specification (Operating mode -4). Regardless of the set val-
ue input setting (

or
Z

) it is always active and in format 16 Bit angle.
Its value is added to the interpolated set value as Delta position (= speed) during each
cycle of the set value interface.

When using the offset speed it must be observed that the input set value and position set
value (

must no longer match.
The parameter must be distinguished from the speed additional set value, which has a
direct effect on the speed control input!
136.8
Output position set value
This parameter shows the calculated target position after offset addition and is updated
during the cycle of the set value interface.
The displayed value is in format 16 bit revo 16 bit angle.
136.9
Output speed set value
This parameter shows the generated output speed set value after offset addition and after
PT
1
smoothing.
The displayed value is in format 16 bits increments/revolution per ms.
136.10
Output acceleration set value
This parameter shows the generated output set value speed after offset addition and is
updated during the cycle of the set value interface.
