Energy saving
The converter can optimize the e󹪟ciency of the motor.

The converter calculates how much energy controlled converter operation saves when
compared to mechanical 󹪞ow control (e.g. throttle).

After switching the supply voltage on, the converter normally goes into the "ready to start"
state. In this state, the converter waits for the command to switch on the motor.
The converter switches on the motor with the ON command. The converter changes to the
"Operation" state.
After the OFF1 command, the converter brakes the motor down to standstill. The converter
switches o󹪜 the motor once standstill has been reached. The converter is again "ready to
start".
