Instruction Manual PSx3xxPL
29
After reaching the target position, this position is compared with the internal absolute
encoder status. If there is a deviation, the status bit "Error" is set (bit 9 in the status
word).
In the delivery state, the loop length is -250, i.e. each setpoint position is approached
in the forward direction.
A positioning to the upper end limit (SDO #2016) with a loop length > 0 is
not possible, since the drive would have to cross the end limit for this. The
same applies to the lower end limit (SDO #2017) with a loop length < 0.
3.2
Positioning run without loop
The "Positioning without looping" mode is mainly used for moving small distances for
fine corrections. Each position is approached directly. Any backlash in the driven
spindle is NOT eliminated. The internal gear backlash of the PSx3xx does not occur
in this case either, since the position measurement takes place directly on the output
shaft.
