* 1. Only 1(VT) can be set for 200 V Class 110 kW as well as 400 V Class 220 kW and 300 kW Inverters.
* 2. The factory settings depend on the capacity of the Inverter. The values for a 200 V Class Inverter of 0.4 kW are given.
* 3. The setting ranges depend on the capacity of the Inverter. The values for a 200 V Class Inverter of 0.4 kW are given.
* 4. This constant can be monitored or set only when F is set for C6-02.
