3.7.5 Pulse Converter: AK-04 (Optional accessory)
This pulse converter is necessary when pulse train control is required and the output pulse of
the host controller is the open collector type. It converts the command pulse of the open
collector type to the differential type.
Use the enclosed e-CON connector for wiring.
The available cable wire size is AWG22 to 26 (less than 0.2 to 0.3mm 2 ) equivalent to KIV,
finished out diameter I1.0 to 1.2mm.

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 surrounding 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 one is easy to pick the noise. Also make the wiring between AK-04 to ERC3 as
short as possible.
Place AK-04 close to the host controller.
A recommended installation sample is shown in the figure below.
Ɣ Make the cable length between the
host controller and pulse converter as
short as possible.
Wiring length :
50mm or shorter recommended
Host Controller
Ɣ 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.
