ORIENTATION CONTROL—A500(L)
3.3 Wiring Instructions
(1) Connection with the position detector (encoder).
Use twisted pair shielded cables (0.2mm
2
or larger) to connect the FR-A5AP and position detector
(encoder). Cables to terminals 5V and SG should be connected in parallel or be larger in size according
to the cable length as indicated in the table below.
To protect the cables from noise, run them away from any source of noise (e.g. the main circuit and
power supply voltage).
(2) Cable length.
1)Cable length within 30m.
2)Cable length of more than 30m.
Use a power supply slightly higher than 5V (approximately 5.5V) in addition to 6 or more parallel
cables of 0.2mm
2
or cables of 1.25mm
2
or more. This allows the cable length to be increased up to
100m. Note that the voltage applied across terminals 5V-SG must not exceed 6V.

3)Connection with NC. (Or similar device)
When one position detector is shared between the
FR-A5AP and NC (or another device), its output sig-
nals should be connected as shown below. In this
case, the cable length between the FR-A5AP and NC
should be as short as possible, within 5m.
