* 1. The factory settings depend on the capacity of the Inverter and the control method. The values for a 200 V Class Inverter for 0.4 kW are given.
* 2. The setting ranges depend on the capacity of the Inverter. The values for a 200 V Class Inverter for 0.4 kW are given.
* 3. This constant can be monitored or set only when F is set for C6-02.
* 4. Displayed in Quick Programming Mode when motor 2 is set for a multi-function input.
* 5. The maximum output frequency depends on the setting for the carrier frequency (refer to page 6-44).
* 6. This setting is for software versions PRG 1040 and later. The factory setting with software versions PRG 1039 and earlier depends on the Inverter
capacity.
