1 INTRODUCTION
The AC0 inverter has been developed for applications such as transpallet trucks, stacker
trucks and cleaning machines with traction motors up to 1.2KW (Vbatt=24V) and 1.8KW
(Vbatt=36V). This model is available in the standard format, using an encoder, but it's also
thought (work in progress) for sensorless control (no shaft encoder is required). The AC0
can directly replace an AC1 inverter having exactly the same I/O connections and param-
eter settings. The only differences are the maximum current (150A vs. 250A), the dimen-
sions, and the input CNA #13 which is reserved for an analogue motor sensor.
