Reset selection (P.E100)
When P.E100 ="1" or Pr. 75 ="1, 3, 15, 17, 100, 103, 115, or 117" is set, reset (reset command via RES sig-
nal or communication) input is enabled only when the protective function is activated.
When the reset signal (RES) 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 regener-
ative brake duty are cleared.
The input of the PU reset key is only enabled when the protective function is activated, regardless
of the P.E100 and Pr. 75 settings.
Disconnected PU detection (P.E101)
If the PU (FR-DU08/FR-PU07) is detected to be disconnected from the inverter for 1 s or longer while
P.E101 = "1" or Pr. 75 = "2, 3, 16, 17, 102, 103, 116, or 117", PU disconnection (E.PUE) is displayed and
the inverter output is shut off.
When the PU has been disconnected since before power-ON, the output is not shut off.
To restart, confirm that the PU is connected and then reset.
When P.E101 = "0" or Pr. 75 = "0, 1, 14, 15, 100, 101, 114, or 115" (operation continues even when
PU disconnected), decelerates to a stop when PU is disconnected during PU JOG operation.
When RS-485 communication operation is performed through the PU connector, the reset selec-
tion/PU stop selection function is valid but the disconnected PU detection function is invalid. (The
communication is checked according to Pr. 122 "PU communication check time interval".)
PU stop selection (P.E102)
● Stop can be performed by inputting
operation, External operation and network operation.
● When stop is performed by the PU stop function, "PS" is displayed on the PU. A fault output is not
● When P.E102 = "0" or Pr. 75 = "0 to 3, 100 to 103" is set, deceleration stop using
in the PU operation mode.
When Pr. 551 "PU mode operation command source selection" = "1" (PU mode RS-485 terminal),
deceleration stop is performed even when
(E) Environment setting parameters
