Tab. 6-86: Output terminal function assignment (5)
Note that when the frequency setting is varied using an analog signal or the digital dial of
the operation panel (FR-DU07), the output of the SU (up to frequency) signal may alternate
on and off depending on that varying speed and the timing of the varying speed due to
acceleration/deceleration time setting. (The output will not alternate on and off when the
acceleration/deceleration time setting is "0s".)
When a power supply reset is performed, the alarm output 2 signal (ALM2) turns off as soon
as the power supply switches off.
Up to frequency SU, frequency detection FU, FU2, FU3 under encoder feed back control or
vector control (option FR-A7AP is mounted) signals are as below.
SU, FU: Output when the actual speed (frequency) by the encoder feedback signal exceeds
detected specification frequency.
FU2, FU3: Output when the inverter output frequency exceeds detected specification
frequency..
This parameter is valid when the FR-A7AP (option) is mounted.
NOTES The same function mag be set to more than one terminal.
When the function is executed, the terminal conducts at the setting of any of "0" to "99", and
does not conduct at the setting of any of "100" to "199".
The signal will not function if a value other than the above is set to any of Pr. 190 to Pr. 196.
When Pr. 76 "Alarm code output selection" = 1, the output signals of the terminals SU, IPF,
OL and FU are switched as set in Pr. 76. (When an inverter alarm occurs, the signal output
is switched to the alarm output.)
The output assignment of the terminal RUN and alarm output relay are as set above regard-
less of Pr. 76.
When terminal assignment is changed using Pr. 190 to Pr. 196 "Output terminal function
selection", the other functions may be affected. Please make setting after confirming the
function of each terminal.
Do not assign signals which repeat frequent ON/OFF to A1, B1, C1, A2, B2, C2. Otherwise,
the life of the relay contact decreases.

Minor fault output 2
LF Minor fault output
Alarm output
— No function
Operation
Output when the inverter pro-
tective function is activated to
stop the output (major fault)
Output when a minor fault
(fan failure or communication
error warning) occurs.
Output when the inverter's
protective function is acti-
vated to stop the output
(major fault). The signal out-
put is stopped when a reset
turns on.
