Parameters
Regenerative status output signal (Y32)
Fig. 5-168:
● When the motor is in the regenerative status (motor is in the dynamic braking status) under vector
control, the Regenerative status output (Y32) signal turns ON. Once it turns ON, the signal is
retained for at least 100 ms.
● The signal turns OFF during a stop or pre-excitation.
● To use 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.
NOTES Always OFF under V/F control, Advanced magnetic flux vector control, Real sensorless vector con-
trol, and PM sensorless vector control.
Fault output signals (ALM, ALM2)
Fig. 5-169:
● The Fault (ALM, ALM2) signals are output when the inverter protective function is activated.
● The ALM2 signal stays ON during the reset period after the fault occurs.
● To use 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.
● The ALM signal is assigned to the A1B1C1 contacts in the initial status.
NOTE For the inverter fault details, refer to page 6-9.
