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
