5.2.2 E codes (Extension Terminal Functions)
E01 to E07 Terminal [X1] to [X7] Function E98 (Terminal [FWD] Function)
E99 (Terminal [REV] Function)
Function codes E01 to E07, E98 and E99 allow you to assign commands to terminals [X1] to [X7], [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." The descriptions 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 FRENIC-MEGA runs under V/f control, dynamic torque vector control, V/f control with speed sensor, dynamic
torque vector control with speed sensor, vector control without speed sensor, or vector control with speed sensor. Some
function codes 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 5-2.)
• 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.
