4-3-3 Installing
The HS-360 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 M5 machine screw in the tapped
hole on the wall.
(2)Put the power mounting hole (cut hole) of
the back of the driver on the M5 screw.
(3)Screw tightly through the upper mounting hole
with M5 screws.
(4)Tighten the lower M5 screw.
4-4 Suppressing noise
The HS-360 driver employs an IPM (power module) with a PWM control for main circuit. As the IPM
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 HS-360 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 as follows:
