115 V/230 V variable frequency drive
With 115 V devices, the input voltage is doubled is doubled inside the device so that the required
maximum output voltage of 230 V is achieved by the device.
The following data refers to a 230/400 V motor winding. They apply for IE1 and IE2 motors. It should
be noted that these details may deviate slightly, as motors are subject to certain manufacturing
tolerances. It is recommended that the resistance of the connected motor is measured by the variable
frequency drive (P208/P220).
