(E) Environment setting parameters
Disconnected PU detection (P.E101)
• When the inverter detects that the PU (operation panel/parameter unit) 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 since before power-ON, the output is not shut off.
• To restart, confirm that the PU is connected and then 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.
• When RS-485 communication operation is performed through the PU connector, the reset selection/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
and network operation.
• When stop is performed by the PU stop function, "
• When P.E102="0" or Pr.75="0 to 3, 100 to 103" is set, deceleration stop using
mode.
NOTE
• When Pr.551 PU mode operation command source selection="1" (PU mode RS-485 terminal), deceleration stop is
performed even when
How to restart after stopping with
operation (PU stop (PS) release method)
• PU stop release method for operation panel
1) After completion of deceleration to a stop, switch OFF the STF and STR signal.
2) three times. (
Press
(When Pr.79 Operation mode selection = "0 (initial value) or 6")
When Pr.79 = "2, 3, or 7",
• PU stop release method for parameter unit
1) After completion of deceleration to a stop, switch OFF the STF or STR signal.
2) . ( release)
Press EXT PS
• The motor can be restarted by resetting the power supply or resetting with a RES signal.
NOTE
• Even when Pr.250 Stop selection  "9999" is set and coasting stop is selected, deceleration stop and not coasting stop is
performed in the PU stop function during External operation.
