Ferrite core
•
When suppressing effect by noise propagation, use a ferrite core.
•
Use the ferrite core for extending the motor cable
Use ferrite core 7427122 by Wurth Electronik GmbH & Co. KG, ZCAT3035-1330
by TDK Corporation or its equivalent.
Connect the ferrite cores as close as possible to the driver.
•
Wiring the signal cable
Use a braided screen cable of AWG26 (0.14 mm
2
) or more in diameter for the driver
signal cable, and keep it as short as possible.
To ground a braided screen cable, use a metal clamp or similar device that will
maintain contact with the entire circumference of the braided screen cable. Attach a
cable clamp as close to the end of the cable as possible, and connect it to an
appropriate grounding point as shown in the figure.

How to ground
The cable used to ground the motor and driver must be as thick and short to the
grounding point as possible so that no potential difference is generated. Choose a
large, thick and uniformly conductive surface for the grounding point.
•
How to ground the motor
Connect the grounding wire along with a set
screw to the grounding point, using a crow
washer.
For the
AXH015
geared type models, remove
the paint from the mounting surface of the geared
motor, and install it to a metal surface that has
grounded.
