*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 alarm 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 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 parameter 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".
⋅ 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 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
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 inverter protective
function is activated to stop the output
(major fault). Continue outputting the
signal during inverter reset and stop
outputting after reset is cancelled.
Output when Pr. 503 rises to or above
the Pr. 504 setting.
Output to the terminal when a value is
set to the parameter.
Output when the inverter protective
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 protective
function is activated to stop the output
(major fault). The signal output is stopped
when a reset turns on.
