• Use the reset function to reset the trip status of the inverter. This function is used also when the
inverter operates normally to shut off the inverter output.
To disable the reset function when the inverter operates normally, set the Reset Selection (C102) to
02 (Enabled only during trip) or 03 (Reset only during trip).
• If the reset signal is input to the inverter, calculated electronic thermal function data, calculated
regenerative braking usage rate data, multi-function pulse counter/current position counter data, and
internal counter data used for the Teaching Selection (P074) and protective function are cleared. To
prevent these data from being cleared, set the Reset Selection (C102) to 03 (Reset only during trip).
• Setting the STOP Key Selection (b087) to 00 (Enabled) or 02 (Only STOP function disabled) enables
the input of the reset signal via the STOP/RESET key on the Digital Operator.
• To input the reset signal via the control circuit terminal block, set the Multi-function Input S1 to S8
Selection (C001 to C008) to 18 (RS: Reset).
• The terminal RS (Reset) only supports NO (normally open contact) as the input method. The
Multi-function Input S1 to S8 Operation Selection (C011 to C018) cannot be set to 01 (NC: Normally
closed contact). Be sure to set the NO contact.
In addition, selecting the Reset Selection (C102) is set to 02 (Trip reset at power-off) enables the
reset function to be activated at the falling edge of the signal.
• In the Reset Restart Selection (C103), select the restart method after reset is executed.
However, when the Reset Selection (C102) is set to 03 (Trip reset only), or when the Reset Restart
Selection (C103) is set to 00 (0-Hz restart), the inverter does not restart.
