Defining the origin Origin search with ORG(889) instruc-
tion
Changing PV with INI(880) instruction
Changing origin • PLC Setup (when power is turned
search parameters ON)
• When INI(880) instruction is executed
Interrupt feeding • Combining ACC(888) + PLS2(887)
instructions
• IFEED(892) instruction
Monitoring output fre- Trend monitoring of output frequencies

Programmer
Actual output fre- Integer division of 33.33 MHz
quency
Update timing for PLC Update timing for origin detection
Setup method: When power is turned ON
Allocation of I/O termi- If not using the origin search is speci-
nals fied, unused terminals can be used for
other functions depending on the oper-
ation mode.
