Power Supply - Mitsubishi Electric FR-A8AP Instruction Manual

 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.
• Specifications of the encoders equipped in the motors with encoders and the vector-control dedicated motors
