31.3 Mechanical OPR
If forward rotation pulses or reverse rotation pulses are generated, the positioning instruction will increase or decrease the
value of the current address.
When the power of the CPU module is turned off, the value stored in the current address will be erased. For this reason, after
turning on the power again, be sure to adjust the value of the current address in the CPU module to the current position of the
machine. The positioning function uses the DSZR/DDSZR instruction (OPR instruction) to adjust the value of the current
address in the CPU module to the current mechanical position.
DSZR/DDSZR
This instruction executes mechanical OPR.
