The ST600 Series VFD carries four programmable digital input terminals and two HDI input terminals.
The function of all the digital input terminals can be programmed by function codes. HDI input terminal
can be set to act as high-speed pulse input terminal or common digital input terminal; if it is set to act
as high-speed pulse input terminal, users can also set HDIA or HDIB high-speed pulse input to serve
as the frequency reference and encoder signal input.

This parameter is used to set the corresponding function of digital multi-function input terminals.
Note: Two different multi-function input terminals cannot be set to the same function.
The VFD does not act even if there is signal input; users can
set the unused terminals to "no function" to avoid misacts.
Control the forward/reverse running of the VFD by external
terminals.
Set the VFD running mode to the 3-wire control mode by this
terminal. See P05.13 for details.
Frequency when jogging, see P08.06, P08.07 and P08.08 for
jogging acceleration/deceleration time.
