3-3-3 Installing
The HA-680 driver should be mounted
on a wall as shown in the figure to the
right.
Two mounting holes are provided on the
back of the driver. The thickness of the
wall should be more than 2mm.
●
Procedure
(1) Screw an M4 machine screw in the
tapped hole on the wall.
(2) Put the lower mounting hole (cut
hole) of the back of the HA-680
driver on the M4 screw.
(3) Screw tightly through the upper
mounting hole with M4 screws.
(4) Tighten the lower M4 screw.
3-4 Suppressing
noise
The HA-680 driver employs a FET (power element) with a PWM control for main circuit. As the element
generates switching noise by high-speed power switching, the noise may cause incorrect motion of
other equipment or radio noise interference due to poor cabling or poor grounding.
In addition, it is necessary to provide proper cable management in order to suppress incorrect motion of
the HA-680 driver by external noise from hosts, which contain electronic components, such as a CPU.
To prevent troubles by noise emissions always install cabling and grounding described below.
