path.
1) Operator or CX-Drive: 0.1 A or 0.1 V (When CX-Drive is operated, set [CF-11] Resister data selection to 00
(A,V). When the data of [CF-11] Resister data selection is not set to 00 (A,V), it is not set or displayed correctly.)
2) Modbus: The current and the voltage vary, depending on the setting of Resister data selection [CF-11].
When [CF-11] Resister data selection is set to 00 (A,V), 0.1 A, 0.1 V
When [CF-11] Resister data selection is set to 01 (%), 0.01% (Rated ratio)
3) Drive programming: 0.01% (Rated ratio)
Sets the threshold level used for detecting
overcurrent.

Trip after Instantaneous Power Interruption/Undervoltage
Item Instantaneous power failure Under-voltage
Always making the inverter trip when an instan-
taneous power failure/under-voltage occurs
Set [bb-20] to 0.
[E016] Instantaneous power
failure error
Set [bb-21] to 0.
[E009] Under-voltage error
Always making the inverter retry when an
instantaneous power failure/under-voltage
occurs
Set [bb-20] to 255. Set [bb-21] to 255.
Making the inverter trip after the specified num-
ber of retries are made after an instantaneous
power failure/under-voltage has occurred
Set [b-20] to other than 0 or
255.
[E016] Instantaneous power
failure error
Set [b-21] to other than 0 or
255.
[E009] Under-voltage error
Outputting the state to an output terminal
Assigns 020 [IP] Instanta-
neous power failure signal.
Assigns 021 [UV] Under-volt-
age signal.
Selecting whether to make the inverter trip
when an instantaneous power failure or
under-voltage occurs while the inverter is in a
stopped state.
