Common Specifications
The
following specifications apply to both 200 V and 400 V Class Inverters.
Note Rotational
autotuning is required to obtain the specifications labeled as open loop vector control.
* 1. Not
including the 200 V Class Inverter for 110 kW and the 400 V Class Inverters for 220 and 300 kW.
* 2. Increase
the Inverter capacity if loads exceeding these current values are expected.
