Selecting Pulse Monitor Items
Output digital operator monitor items (U1-
to Chapter 5 User Parameters, and set the
tions are limited as follows: U1-01, 02, 05, 20, 24, 36.
Adjusting the Pulse Monitor Items
Adjust the pulse frequency output from pulse monitor terminal MP-AC. Set the pulse frequency output when
100% frequency is output to H6-07.
Set H6-06 to 2, and H6-07 to 0, to output the frequency synchronous with the Drive's U-phase output.
Application Precautions
When using a pulse monitor parameter, connect a peripheral device according to the following load condi-
tions. If the load conditions are different, there is a risk of characteristic insufficiency or damage to the
machinery.

the list of U1 monitors.
Sets the number of output pulses
when the monitor is 100% (inHz).
Set H6-06 to 2, and H6-07 to 0, to
make the pulse train monitor output
synchronous to the output
