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 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.
3)Connection with NC. (Or similar device)
When one position detector is shared between the
FR-A5AP and NC (or another device), its output
signals 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.
