3 Precautions for use
This section covers limitations and requirements the user should consider when using the product.
Power capacity
For the controller, use a DC power supply capable of supplying 24 VDC ±5% at 0.45 A or greater, with
reinforced insulation provided on the primary and secondary sides.
Connecting the
OP300
operational unit
Be sure to use the cable supplied with the
OP300
operational unit when connecting it to the controller.
The cable comes with two ferrite cores intended for noise prevention. Do not remove these ferrite cores,
since doing so may diminish noise resistance and possibly cause a malfunction.
Preventing electrical noise
Take the following anti-noise measures to prevent malfunction of the controller, driver, and motor due to
external noise:
• Wiring the I/O cable
For I/O cables, use a shielded cables with connectors (sold separately).
Minimize the length of the I/O cable.
Wire the I/O cables by maintaining a minimum distance of 300 mm (11.8 in.) from the inductive loads of
electromagnetic relays, etc., as well as the power lines (the power supply and motor, etc.). Do not wire
the I/O cables in the same duct or pipe in which power lines are wired.
•
Connecting mains filter for power supply line
Connect a noise filter on the input side of the DC power supply to prevent external noise from being
transmitted to the controller via the power supply line.
Ground the noise filter’s contact terminal using a cable of AWG18 (0.75 mm
2
) or more in diameter. The
use of a cable smaller than AWG18 may cause heat generation.
