*1 Set Pr.73, Pr.267, and the voltage/current input switch correctly, then input an analog signal in accordance with the setting. (Refer to the
Instruction Manual (Detailed) of the inverter.)
Applying a voltage with the voltage/current input switch ON (current input is selected) or a current with the switch OFF (voltage input is
selected) could cause component damage of the inverter or analog circuits of output devices.

Terminal function description
Input power for the encoder power supply.
Connect the external power supply (5 V, 12 V, 15
V) and the encoder power cable. 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.)
Short terminals PG24 and PG for using the 24
VDC power supply of the FR-A8TP.
For connecting a 24 V external power supply.
If a 24 V external power supply is connected,
power is supplied to the control circuit while the
main power circuit is OFF.
