(2) Forward rotation and reverse rotation
signal (Y30, Y31)
The status during forward rotation (Y30) and reverse
rotation (Y31) are output from the actual motor speed
under vector control.
Y30 and Y31 signals turn OFF during pre-excitation
(zero speed, servo lock) under speed control or
torque control operation. Note that signals are output
according to the motor rotation during servo lock
under position control as same as inverter running.
When using the Y30, Y31 signal, set 30, 31 (positive
logic) or 130, 131 (negative logic) in any of [Pr. 190 to
Pr. 196 Output terminal function selection] to assign the
function to the output terminal.
*1 This signal is always OFF during V/F control,
Advanced magnetic flux vector control or Real
sensorless vector control.
*2 If the motor is made to run by external force, etc.
during an inverter stop, Y30 and Y31 remain OFF.
*3 The FR-A7AP (option) is necessary for vector
control.

(3) Regenerative mode output signal (Y32)
A700
While the motor is in regeneration status (motor is in
power regeneration status), the regenerative status
output signal (Y32) is turned ON.
If the signal is turned ON once, it will be retained for
at least 100ms.
It turns OFF while the inverter is stopped and during
pre-excitation.
When using the Y32 signal, set 32 (positive logic) or
132 (negative logic) in any of [Pr. 190 to Pr. 196 Output
terminal function selection] to assign the function to the
output terminal.

(4) Fault output (ALM, ALM2)
(* ALM2 is not available for
If the inverter comes to a fault stop, the ALM and
ALM2 signals are output. The ALM2 signal remains
ON during a reset period after fault occurrence.
When using the ALM2 signal, set 94 (positive logic)
or 194 (negative logic) in any of [Pr. 190 to Pr. 196
Output terminal function selection] to assign the
function to the output terminal.

(5) Instantaneous power failure/undervoltage
(IPF)
A700
When instantaneous power failure protection (E.IPF)
and undervoltage protection (E.UVT) are activated,
the inverter trips. (Refer to page 97 for E.IPF and
E.UVT)
When E.IPF and E.UVT are activated, instantaneous
power failure/under voltage signal (IPF) is output.
