4.1.10. Prevention of Malfunction by Noise
CAUTION
• Be sure to install a serge absorber circuit to a coil such as a relay, electromagnetic
contacting machine, induction motor, and break solenoid.
• Do not bundle the power supply line, motor line, and signal lines together or do not
lay them in the same duct.
• Take the following steps if the noise environment is poor or if CE conformity is
required
Attaching a ferrite core to the A connection cable
Attach the ferrite core as shown in the diagram below.
Electric gripper
control board
Install the accompanied ferrite core as close as possible to the electric
gripper control board. Pass the electric gripper connection cable
through the ferrite core (large) three times, and then bundle the cable
with tie bands (small) at the both side of the ferrite core to prevent
cables from loosening (see the figure below).
After that, with the accompanied tie band (large), fasten the ferrite core
(large) to the position to prevent the loads being applied to the electric
gripper connection cable.

passed through the ferrite core three times.
