Setup : Start position 0
Target postion = 3000
Setup : Start position 0
Target postion = 3000
Setup: Start position 0
Target postion = 19000
Result: P_SOLL = 3000
since the remainder after
19000 / 8000 is 3000.
Setup: Start position 0
Target postion = -21000
Result: P_SOLL = 5000
since the remainder after
21000 / 8000 is 5000.
Setup : Start position 0
Target postion = 5000
Setup : Start position 0
Target postion = 5000
Setup : Start position 3000
Target postion = -1000
Result: Actual position (P_SOLL)
=0 since the value is limited to
the working range minimum
Setup : Start position 5000
Target postion = 12345
Result: Actual position (P_SOLL)
= 7999 since the value is
imited against the working
range maximum
In general, Actual position (P_SOLL) will be modified to be within the valid rotary table position working range
if a value outside this range is written to the Actual position register (P_SOLL).
When using the multiturn options (4 and 5) the position is limited as follows:
- Multiturn CW rotation (4). Values below working range minimum are limited to the minimum.
- Multiturn CCW rotation (5). Values above working range maximum are limited to the maximum.
Setup : Start position 3000
Target postion = 0
Setup : Start position 5000
Target postion = 0
Basic setup:
Working range min./max= 0 to 7999 counts
equal to one revolution.
