*1. On the parameter about the current and the voltage, the figures and the units to be handled vary in the setting 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)
*2. 1.8 × Inverter rated current (A)
*3. 1.5 × Inverter rated current (A)
*4. Minimum resistance values vary in inverter model.
