7 PO-01 Module Specification and Handling
7.2.4 Out-of-step Detection
7-26
„ Application Program Example
The monitor parameter from the PO-01 Module (number of output pulses: IL††2A) and
input data from the Counter Module (CNTR-01) (number of incremental pulses: IL††02)
are used to create an out-of-step detection program in a high-speed scan program
(DWG.H††).
Axis 1 of PO-01 Module number 1 is used in this example. Be sure to change the register
number of the monitor parameter (ILC02A) if you use another axis.
CNTR-01 Module input data is allocated from IW1000 to IW100F. Be sure to change the
register number of the input data (IL1002) if you use another allocation. Set the Counter
Mode to Frequency Measurement.
