Reset (Rs) - Hitachi L300P-110L Instruction Manual

Reset (RS)

This function resets the inverter when a protective trip has occurred.
The method of reset is to either push the STOP/RESET key on the
digital operator or to switch the RS terminal ON.
To reset the inverter with the control terminal, assign 18(RS) to an
intelligent input terminal.
Reset frequency matching selection C103 selects whether the inverter restarts
at 0Hz or the inverter matches the output frequency after the reset operation is complete.
Reset selection C102 selects when the alarm signal is cancelled and whether it is valid or invalid in normal
operation.
The RS terminal is valid only when the contact is set to NO.
