(A) Application parameters
Machine end orientation connection diagram (Vector control)
To perform machine end orientation control, the following settings are required.
– Install a plug-in option (FR-A8AP or FR-A8APR) and a control terminal option (FR-A8TP) to the
inverter, a motor end encoder to the control terminal option, and a machine end encoder to the
plug-in option.
– Set Pr. 862 "Encoder option selection" = "1".
– Set Pr. 393 "Orientation selection" = "10 to 12" (refer to page 5-535).
– Set the gear ratio by setting Pr. 394 "Number of machine side gear teeth" and Pr. 395 "Number of
motor side gear teeth" (refer to page 5-542).

The power supply of the fan for a 7.5 kW or lower dedicated motor is single phase. (200 V/50 Hz,
200 to 230 V/60 Hz)
The pin number differs according to the encoder used.
Use Pr. 178 to Pr. 182, Pr. 185, or Pr. 189 (input terminal function selection) to assign the function
to a terminal. (Refer to page 5-439.)
Use Pr. 190 to Pr. 192, or Pr. 195 (output terminal function selection) to assign the function to a
terminal. (Refer to page 5-378.)
Connect the encoder so that there is no looseness between the motor and motor shaft. Speed
ratio must be 1:1.
Earth (ground) the shield of the encoder cable to the enclosure using a tool such as a P-clip. (Refer
to page 2-81.)
