 Power supply
Prepare an encoder's power supply (5 V, 12 V, 15 V, etc.) according to the encoder to be used. When the encoder output is the
differential line driver type, only 5 V can be input. Make the voltage of the external power supply same as the encoder output
voltage. (Check the encoder specification.) Use terminal PG24 for the 24 V encoder's power supply.
The encoder's power supply is shared under orientation control, encoder feedback control or vector control.
• Specifications of the encoders equipped in the motors with encoders and the vector-control dedicated motors

NOTE
• When the input power supply voltage to the encoder and its output voltage differ, the protective function (E.ECT) may be
activated.
• When an external power supply is used for the encoder, turn OFF the encoder's power supply while power is not supplied to
the control circuit of the inverter. Otherwise, the plug-in option may be damaged.
