High-function General-purpose Inverter RX2 Series User’s Manual
(Ex.6) When [bb-20] ≠00 and [bb-24] = 04, it restarts by picking up the frequency, and then after decel-
eration according to the setting, the motor trips when stopped.
Note The motor will trip after instantaneous power failure allowable time.
In case of overcurrent, you can restart without causing tripping.
Precautions for Correct Use
If overcurrent continues to be observed, there are some possible causes: short acceleration
time, heavy load, locked motor, etc.

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].
