detect any target signals (e.g. a limit switch) or the home position within this search
distance, it will issue an error message.
Max. position limits
If this button is clicked, the search distance will be determined based on the maximum
position limits.
Offset start position
The actual home position, i.e. the mathematical zero point for the subsequent positioning
runs, is slightly offset from the reference point of the homing run. This offset is stated
under
Offset start position . At first, this offset value leads to a shift of the actual position.
To ensure that the drive actually moves to this position, Go to zero position after homing
(see above) must be activated.
Actual position of multi-turn encoders
In the case of multi-turn encoders, the current actual position is preserved even if the
supply voltage is switched off, provided that the multi-turn range is not exceeded.
However, it is useful to shift this position, e.g. when setting up the machine.
The firmware includes an offset parameter for this case. It can be stored in the internal
parameter set of the encoder. The offset parameter can be redetermined by way of a
homing run and then stored in the encoder parameter set.
