(3) Connection of terminal resistors.
Use the jumpers across PA2-PAR, PB2-PBR and PC2-PCR to connect terminal resistors to the A, B
and C-phases of the encoder. Normally, keep the jumpers fitted.
However, remove the jumpers when the same encoder is shared between the FR-A5AP and the other
unit (e.g. NC) which is connected with a terminal resistor.
(4) Position detector (encoder).

<Example of encoder available on the market>
Use an encoder which has an output circuit equivalent to AM26LS31 or 74LS113.

CAUTION
When encoder feedback control and orientation control are used together, the encoder is shared
between these controls.
Use an encoder which has a pulse count of 1000 to 4096ppr (pulses per revolution).
