5.3.2 E codes (Extension terminal functions)
E01 to E09
Terminal [X1] to [X9] (Function selection)
Related function codes: Terminal E98 [FWD] function
Terminal E99 [REV] function
E01 to E09, E98 and E99 assign commands to general-purpose, programmable, digital input terminals, [X1] to [X9],
[FWD], and [REV].
These function codes can also switch the logic system between normal and negative to define how the inverter
logic interprets the ON or OFF state of each terminal. The factory default setting is normal logic system “Active ON.”
Functions assigned to digital input terminals [X1] to [X9], [FWD] and [REV] are as shown below. Descriptions that
follow are given in normal logic system. Each signal has been described at data allocation order. However, the
signal is related has been described together. Refer to the function codes in the “Related function codes” column,
if any.
By setting the same data as that shown in the following table for function code E70, terminal functions indicated
with a “Y” in the “Operation possible with M/Shift key” column can be turned ON and OFF manually by assigning
the functions to the M/Shift key on the keypad.
Refer to the explanation on function code E70 for details.
• Run commands (e.g., Run forward “FWD”), stop commands (e.g., coast to stop “BX”), and frequency change
commands can be assigned to digital input terminals. Depending on the digital input terminal status, operation
may start suddenly, or the speed may change significantly simply by changing the function code settings.
Make changes to function code settings after sufficiently ensuring safety.
• Functions for switching run or frequency command sources (such as “SS1, SS2, SS4, SS8”, “Hz2/Hz1”,
“Hz/PID”, “IVS” and “LE”) can be assigned to the digital input terminals. Switching these signals may cause a
sudden motor start or an abrupt change in speed depending on the condition. Depending on the conditions,
changes to these signals may result in operation being started suddenly or the speed changing suddenly.
Failure to observe this could result in an accident or injury.
