E01 to E03
Terminal [X1] to [X3] Function
E98, E99
Terminal [FWD] and [REV] Function
Function codes E01 to E03, E98 and E99 allow you to assign commands to terminals [X1] to
[X3], [FWD], and [REV] which are general-purpose, programmable, digital input terminals.
These function codes may also switch the logic system between normal and negative to
define how the inverter logic interprets either ON or OFF status of each terminal. The default
setting is normal logic system "Active ON." So, explanations that follow are given in normal
logic system "Active ON."
In the case of digital input, you can assign commands to the switching means for the run
command and its operation and the reference frequency (e.g.,
SS1
,
SS2
,
SS4
,
SS8
,
Hz2/Hz1
,
Hz/PID
,
IVS
, and
LE
). Be aware that switching any of such signals may cause a
sudden start (running) or an abrupt change in speed.
An accident or physical injury may result.

Any negative logic (Active OFF) command cannot be assigned to the functions
marked with "
" in the "Active OFF" column.
The "Enable external alarm trip" and "Force to stop" are fail-safe terminal commands.
For example, when data = 9 in "Enable external alarm trip," "Active OFF" (alarm is
triggered when OFF); when data = 1009, "Active ON" (alarm is triggered when ON).
