 Power supply
Choose a power supply for encoder according to the encoder used (5 V/12 V/15 V/24 V). When the encoder output is the
differential line driver type, only 5 V can be input. Make sure the voltage of the external power supply the same as the encoder
output voltage. (Check the encoder specification.)
When an encoder is used under orientation control, encoder feedback control, and vector control, the power supply is shared
between the inverter and encoder.

NOTE
• When the input power supply voltage to the encoder and its output voltage differ, the protective function (E.ECT) may be
activated.
