N700E INSTRUCTION MANUAL
Unattended Start Protection [USP]
• If the Run command is already set when power is turned on, the inverter starts running immediately
after power up.
The Unattended Start Protection (USP) function prevents that automatic start up, so that the inverter will not
run with-out outside intervention.
To reset an alarm and restart running, turn the Run commend off or perform a reset operation
by the terminal[RS] input or the keypad Stop/reset key.
• In the figure below, the [UPS] feature is enabled. When the inverter power turns on, the motor does
not start, even though the Run command is already active.
Instead, it enters the USP trip state, and displays E13 error code.
This forces outside intervention to reset the alarm by turning off the Run command.
Then the Run command can turn on again and start the inverter output.

Required setting
Notes:
• Note that when a USP error occurs and
it is canceled by a reset from a [RS]
terminal input, the inverter restarts running
immediately.
• Even when the trip state is canceled by
turning the terminal [RS] on and off after
an under voltage protection E09 occurs,
the USP function will be performed.
• When the running command is active
immediately after the power is turned on,
a USP error will occur. When this function
is used, wait for at least three seconds after
the power up to generate a Run command.
