4.2.2 E codes (Extension Terminal Functions)
E01 to E07 Terminal [X1] to [X7] Function
E98 (Terminal [FWD] Function)
E99 (Terminal [REV] Function)
E01 to E07, E98 and E99 assign commands (listed below) to general-purpose, programming, 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.
The EQ7 runs under "V/f control," "dynamic torque control," "vector control without speed sensor," or "vector
control with speed sensor." Some terminal commands assigned apply exclusively to the specific drive control,
which is indicated by letters Y (Applicable) and N (Not applicable) in the "Drive control" column in the table given
below. (Refer to page 4-2.)
• Ensure safety before modifying the function code settings.
Run commands (e.g., "Run forward"
FWD ), 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 , and LE ) may cause a
sudden motor start or an abrupt change in speed.
An accident or physical injury may result.
