8-3-4 Power Recovery Restart Prevention Function (USP)
This function allows you to make the inverter trip with error code [E13] displayed if the inverter power is
turned on when an operation command has been turned on.
You can recover the inverter from tripping by performing the reset operation or turning the operation
command off. (Ex.1)
If the inverter is recovered from tripping with the operation command left turned on, the inverter will start
operation immediately after recovery. (Ex.2)
The inverter can operate normally when an operation command is turned on after the inverter power is
turned on. (Ex.3)
Precautions for Correct Use
• Unlike other types of trip, the USP error [E013] automatically clears when the operation com-
mand is turned off.
• The power recovery restart prevention function operates for 2 seconds at maximum after the
control power is input.
 Parameter
By the setting of the overcurrent detection level [bb160], you can adjust the threshold current value
used for detecting the overcurrent error [E001].
Precautions for Correct Use
If the threshold level for overcurrent is lowered, the overcurrent error [E001] is more likely to
occur. Therefore, it is necessary to lower the levels for the overload restriction function and the
overcurrent suppression function. For details, see 8-2 Tripless Functions on page 8-40.
