2.3.4 Connection of Pulse Train Signal
Pulse train is input to PIO connector.
Insert the wires to the indicated pin numbers.
[Refer to 2.2.3 [4] Circuits for Pulse Train Control]
If the output pulse of the host controller is open collector type, use the following pulse
converter.
Ɣ Pulse converter : AK-04 (to be purchased separately)
It converts the command pulse of the open collector type to the differential type.
 
Caution
1) Pay attention not to insert wrongly because it is the same e-CON connector as input and
output. Putting the power on with the insertion being wrong will burn AK-04.
2) Use the pulse converter in the ambient temperature range between 0qC and 40qC.
3) The temperature increase of about 30qC occurs during operation. Accordingly, neither
install several pulse converters in close contact nor install them within a duct. Do not
install the pulse converter near other heating devices.
4) If more than one pulse converters are installed, set a pulse converter apart from another by
10mm or more.
5) Make the wiring between the host controller (PLC, etc.) and AK-04 as short as possible.
Long wires make it easy to pick up noise. Also make the wiring between AK-04 to
PCON-CA/CFA as short as possible.
Place AK-04 close to the host controller.
A recommended installation sample is shown in the figure below.
• Make the cable length between the host
controller and pulse converter as short as
possible.
Wiring length :
50mm or shorter recommended
Host Controller
• Keep pulse converters separated for 10mm or
more from each other.
10mm or more
10mm or more
If this installation cannot be
avoided, shorten the length of
the wiring with the host
controller as much as possible.
