PARAMETERS
3.5.16
Reset selection / disconnected PU detection /
PU stop selection (Pr.75)
 Reset selection
• The conditions where the reset command is enabled (using the RES signal or through communication) can be selected.
• When
Pr.75 is set to any of "1, 3, 15, and 17", the reset input is enabled only when the protective function is activated.
NOTE
• When the RES signal is input during operation, the inverter is also reset. The motor coasts since the inverter being reset
shuts off the output. Also, the cumulative value of the electronic thermal relay is cleared.
• The reset input by using the reset key on the PU on the converter is enabled only when the protective function is activated,
regardless of the Pr.75 setting.
 Disconnected PU detection
• If the converter detects that the operation panel has been disconnected for 1 second or longer, the protective function (E.J)
is activated and the converter output is shut off.
• When Pr.75 is set to any of "0, 1, 14, and 15", operation continues even if the PU is disconnected.
NOTE
• When the PU has been disconnected before power-ON, the fault is not activated.
• To restart operation, make sure that the PU is connected before reset.
• When RS-485 communication operation is performed through the PU connector, the reset selection/PU stop selection
function is enabled but the disconnected PU detection function is disabled.
 PU stop selection
• The converter operation can be stopped by pressing on the PU when Pr.75 = "14 to 17".
• When the operation is stopped by the PU stop, the "LD" is displayed on the operation status 7-segment LED display of the
converter (and "PS" is displayed on the PU). A fault output is not provided.
The reset input acceptance, disconnected PU connector detection function, and PU stop function can be selected.
