Pulse Train Input Operation - Hitachi WJ200 Series Quick Reference Manual

Pulse Train Input Operation

The WJ200 inverter is capable of accepting pulse train input signals, that are used for
frequency command, process variable (feedback) for PID control, and simple positioning.
The dedicated terminal is called "EA" and "EB". Terminal "EA" is a dedicated terminal, and
the terminal "EB" is an intelligent terminal, that has to be changed by a parameter setting.

EA Pulse train input A
EB Pulse train input B
(Input terminal 7)
(Set
(1) Frequency Command by pulse train input
When using this mode, you should set
input-capture, and calculated based on the ratio of designated max. frequency (under
32kHz). Only an input terminal "EA" will be used in this case.
(2) Using for process variable of PID control
You can use the pulse train input for process variable (feedback) of PID control. In this
case you need to set
(3) Simple positioning by pulse train input
This is to use the pulse train input like an encoder signal. You can select three types of
operation.
