 Reset selection (P.E100)
• When P.E100 = "1" or Pr.75 = "1, 3, 15, or 17" is set, the reset command input is enabled (using the RES signal or through
communication) only when the protective function is activated.
NOTE
• When the RES signal is input during operation, the motor coasts since the inverter being reset shuts off the output. Also, the
cumulative values of electronic thermal O/L relay and regenerative brake duty are cleared.
• When "reset input always enabled" is selected, the reset key on the PU is enabled only when the protective function is
activated.
 Disconnected PU detection (P.E101) (standard model only)
• When the inverter detects that the PU connector is disconnected from the inverter for 1 second or more while P.E101 =
"1" or Pr.75 = "2, 3, 16, or 17", the PU disconnection ("E.PUE") indication is displayed and the inverter output is shut off.
NOTE
• When the PU has been disconnected before power-ON, the output is not shut off.
• To restart the inverter operation, confirm that the PU is connected before reset.
• When the inverter detects that the PU is disconnected during PU JOG operation while P.E101 or Pr.75 is set to continue the
inverter operation even when the PU is disconnected, the inverter decelerates the motor to stop.
• During RS-485 communication operation via the PU connector, the Reset selection function and the PU stop selection function
are enabled but the Disconnected PU detection function is disabled. (The communication is checked according to Pr.122 PU
communication check time interval.)
• PU disconnection detection function is unavailable for Ethernet models.

Description
In the initial setting, the reset command input is always enabled,
the inverter operation continues even when PU is disconnected,
and the operation can be stopped on the PU.
Reset input is always enabled.
Reset input is enabled only when the protective function is
activated.
Operation continues even when the PU is disconnected.
The inverter output is shut off when the PU is disconnected.
The inverter decelerates to stop when the STOP key on the PU is
pressed in PU operation mode. (The PU stop function is disabled.)
The inverter decelerates to stop when the STOP key on the PU is
pressed in any operation mode of the PU, external, or Network.
(The PU stop function is enabled.)
