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.
• The following table shows applicable start commands. (When both the STF and STR signals are ON, the start signal status is
OFF.)

Communication
 Disconnected PU detection (P.E101)
• When the inverter detects that the PU (FR-DU08/FR-PU07) is disconnected from the inverter for 1 second or more while
P.E101 or Pr.75 is set to shut off the inverter output upon disconnection of the PU, 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 a 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 stop selection (P.E102)
• When the PU stop function is enabled, the motor can be decelerated to a stop by pressing
External, or Network operation mode.
• The table below describes situations in which the PU stop function is activated. The indication "
