*1 Note that when the frequency setting is varied using an
analog signal or setting 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".)
*2 Up to frequency SU, frequency detection FU, FU2, FU3
under encoder feedback control or vector control (option
FR-A7AP is mounted) signals output 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.
*3 When a power supply reset is performed, the alarm
output 2 signal (ALM2) turns OFF as soon as the power
supply switches OFF.
Functions
Output when an alarm (fan failure or communication
error warning) occurs.
Output when the inverter protective function is
activated to stop the output (fault).
The signal output is stopped when the fault is reset.
Operation
—
*4 Available only when used with the FR-A7AP or FR-A7AL
(option).
*5 This can be assigned to only when the FR-A7AY or FR-
A7AR (option) is mounted. This cannot be set to [Pr. 190
to Pr. 196 ]
*6 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.
*7 When [Pr. 76 Fault code output selection = 1] in
, the output signals of terminals SU, IPF,
A700 F700
OL and FU are switched as set in [Pr. 76]. (When an
inverter fault occurs, the signal output is switched to the
fault output.)
*8 Changing the terminal assignment using [Pr. 190 to Pr.
196, Pr. 313 to Pr. 322 Output terminal function selection]
may affect the other functions. Please make setting after
confirming the function of each terminal.
*9 Do not assign signals which repeat frequent ON/OFF to
the relay output terminal. Otherwise, the life of the relay
contact decreases.
