E codes (Extension terminal functions)

E01 to E07 Terminal [X1] to [X7] Functions
E01 to E07, E98 and E99 assign commands (listed below) to general-purpose, programmable,
digital input terminals, [X1] to [X7], [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." So, descriptions that follow are given in normal
logic system. They are, in principle, arranged in the numerical order of assigned data.
However, highly relevant signals are collectively described where one of them first appears.
Refer to the function codes in the "Related function codes" column, if any.
• Ensure safety before modifying the function code settings.
Run commands (e.g., "Run forward" FWD and "Fire mode" FMS), stop commands (e.g.,
"Coast to a stop" BX), and frequency change commands can be assigned to digital input
terminals. Depending upon the assignment states of those terminals, modifying the function
code setting may cause a sudden motor start or an abrupt change in speed.
• When the inverter is controlled with the digital input signals, switching run or frequency
command sources with the related terminal commands (e.g., SS1, SS2, SS4, SS8, Hz2/Hz1,
Hz/PID, IVS, LE and FMS) may cause a sudden motor start or an abrupt change in speed.
An accident or physical injury may result.
