Mitsubishi Electric 800 Series Instruction Manual page 133

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, 17, 10002, 10003, 10016, or 10017", 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 the Ethernet model and the safety communication model.
 PU stop selection (P.E102)
• The inverter operation can be stopped in any operation mode (PU, External, or Network) by pressing the STOP/RESET
key on the operation panel.
• When the inverter is stopped by the PU stop function, "PS" is displayed on the operation panel. However, the Fault signal
is not output.
• When P.E102 = "0", or Pr.75 = "0 to 3 or 10000 to 10003", only the inverter in the PU operation mode decelerates to stop
by pressing the STOP/RESET key.
NOTE
• The inverter decelerates to stop (PU stop function) also when the start command is input using a device which has the
command source (set in Pr.551) and then the STOP/RESET key is pressed on a PU which does not have the command
source.
(Example) When the operation panel has the command source and the stop command is input using a USB (FR
Configurator2), the PU stop function is activated.
 How to restart the inverter which has been stopped in the External
operation mode by using the STOP/RESET key on the PU ("PS" (PU stop)
warning reset method)
• PU stop release method for operation panel
1.
After completion of deceleration stop, turn OFF the STF and STR signals.
