Mitsubishi Electric FR-A820-00046 Instruction Manual page 585

Parameters
Take caution when changing the frequency setting with an analog signal or the setting dial of the
operation panel (FR-DU08), because this change speed and the timing of the change speed
determined by the acceleration/deceleration time setting may cause the output of the SU (up to
frequency) signal to switch repeatedly between ON and OFF. (This repeating does not occur when
the acceleration/deceleration time setting is "0 s".)
The setting is available only for standard models.
This signal cannot be assigned to the output terminals for plug-in options (FR-A8AY, FR-A8AR).
Available when the plug-in option or control terminal option is connected.
The setting is available only for standard models and IP55 compatible models.
The setting can be used for Pr. 313 to Pr. 322 for the FR-A800-GF or when an option (FR-A8AY,
FR-A8AR, FR-A8NC, or FR-A8NCE) is installed. For the corresponding parameters of each option,
refer to the Instruction Manual of the option.
When the power is reset, the fault output 2 signal (ALM2) turns OFF at the same time as the power
turns OFF.
FR-A800-E only.
NOTES The same function may be set to more than one terminal
The terminal conducts during function operation when the setting is "0 to 99, 200 to 299", and
does not conduct when the setting is "100 to 199, 300 to 399".
When Pr. 76 "Fault code output selection" = "1", the output signals of terminals SU, IPF, OL and FU
operate according to Pr. 76 setting. (When the inverter's protective function is activated, the signal
output switches to fault code output.)
The outputs of terminal RUN and the fault output relay are assigned according to the settings
above, regardless of Pr. 76.
Changing the terminal assignment using Pr. 190 to Pr. 196 (output terminal function selection)
may affect the other functions. Set parameters after confirming the function of each terminal.
Do not assign signals which repeat frequently between ON and OFF to terminals A1B1C1 or
A2B2C2. The life of the relay contacts will be shortened.
