 Regenerative status output (Y32) signal
• When the motor gets in a regenerative braking (dynamic braking) state under Vector control, the Regenerative status
output (Y32) signal turns ON. Once the signal turns ON, the signal is retained ON for at least 100 ms.
• The signal is OFF during an inverter stop or during pre-excitation.
• To use the Y32 signal, set "32" (positive logic) or "132" (negative logic) in any parameter from Pr.190 to Pr.197 (Output
terminal function selection) to assign the function to an output terminal.

NOTE
• The Y32 signal is always OFF under V/F control, Advanced magnetic flux vector control, Real sensorless vector control, and
PM sensorless vector control.
 Fault output (ALM) signal
• The fault signal (ALM signal) is output when an inverter protective function is activated.
• The ALM signal is assigned to the terminals A, B, and C in the initial status.
