PARAMETERS
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.
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 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 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 from the PU in any of the operation modes of PU operation, External operation
and network operation.
• When stop is performed by the PU stop function, " " is displayed on the PU. A fault output is not provided.
• When P.E102="0" or Pr.75="0 to 3, 100 to 103" is set, deceleration stop using is valid only in the PU operation
mode.
NOTE
• When Pr.551 PU mode operation command source selection="1" (PU mode RS-485 terminal), deceleration stop is
performed even when is input during operation in PU mode via RS-485 communication.
How to restart after stopping with input from the PU during External
operation (PU stop (PS) release method)
• PU stop release method for operation panel (FR-DU08)
1)After completion of deceleration to a stop, switch OFF the STF and STR signal.
2)
Press three times. ( release)
(When Pr.79 Operation mode selection = "0 (initial value) or 6")
When Pr.79 = "2, 3, or 7",
PU stop can be released by pressing one time.
• PU stop release method for parameter unit (FR-PU07)
1)After completion of deceleration to a stop, switch OFF the STF or STR signal.
2)
Press . ( release)
• 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.
