*1 When the motor with encoder used is other than the standard motor with encoder (SF-JR), the pin numbers are
different.
To reduce radiation noise, connect the shielded wires of the encoder cables to the cable earth (ground) pin.
*2 When encoder feedback control is used with orientation control, the encoder and 5V power supply may be shared
between these controls.
*3 Couple the encoder in line with the motor with a speed ratio of 1 to 1 without any mechanical looseness.
*4 Keep the accessory jumpers connected.
However, when the same encoder is shared between the FR-A5AP and the other unit (e.g. NC) which is connected
with a terminal resistor, the built-in terminal resistors are not required and should be removed. (Terminal resistors;
