*1
Note that when the frequency setting is varied using an analog signal or
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
When a power supply reset is performed, the fault output 2 signal (ALM2) turns off as soon as the power supply switches off.
*3
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.
*4
This function is valid when the FR-A7AP (option) is mounted.
REMARKS
⋅ The same function may 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".
⋅ When Pr. 76 Fault 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 fault occurs, the signal output is switched to the fault code output.)
⋅ The output assignment of the terminal RUN and alarm output relay are as set above regardless of Pr. 76.
CAUTION
⋅ 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.
Function
Output when any of the control circuit
capacitor, main circuit capacitor and inrush
current limit circuit or the cooling fan
approaches the end of its service life.
Output when a fault occurs due to the circuit
failure of the inverter wiring mistake.
Turned on and off alternately every time the
power saving average value is updated when
the power saving monitor is used.
Cannot be set to Pr. 195 and Pr. 196 (relay
output terminal).
Average current value and maintenance timer
value are output as pulses.
Cannot be set to Pr. 195 and Pr. 196 (relay
output terminal).
Output when the fault occurs. Continue
outputting the signal during inverter reset and
stop outputting after reset status is finished.
Output when Pr. 503 rises to or above the Pr.
504 setting.
Output to the terminal when a value is set to
the parameter.
When Pr. 875 = "0" (initial value), the signal is
output when the fault occurs.
When Pr. 875 = "1", the signal is output when
the inverter protective function is activated at
occurrence of OHT/THM/PTC fault and
deceleration is started.
Output when other protective functions are
activated and the inverter trips.
Output when an alarm fault (fan failure or
communication error warning) occurs.
Output when the fault occurs. The signal output
is stopped when the fault is reset.
