[Speed setting switch]
Two different operating speeds of high speed and low speed can be set in the
CVD
driver SC type.
It defines the high speed side as "Speed1" and the low speed side as "Speed2”
to be as follows.
y
Speed1 ...........Operating speed at the high speed side for when the M0 input
is turned OFF.
y
Speed2 ...........Operating speed at the low speed side for when the M0 input
is turned ON.

Two setting patterns are available for the Speed1 and Speed2, and they vary
depending on the setting of the SPD2 EN switch (function setting switch
No.2).

Conformity to the EMC Directive
Effective measures must be taken against the EMI that the motor and driver
may give to adjacent control-system equipment, as well as the EMS of the
motor and driver itself, in order to prevent a serious functional impediment in
the machinery. The use of the following installation and wiring methods will
enable the motor and driver to be compliant with the EMC directive. Refer to
p.11 for the applicable standards.
Oriental Motor conducts EMC measurements on its motors and drivers in
accordance with the "Example of motor and driver installation and wiring" in
the below.
The user is responsible for ensuring the machine's compliance with the EMC
Directive, based on the installation and wiring explained below.
•
Power supply
The
CVD
driver SC type is a product of DC power input. Use a DC power
supply (switched-mode power supply etc.) that conforms to the EMC
Directive.
•
Connecting the signal cable
Refer to "Prevention of noise propagation" on p.8.
•
How to ground
y
The cable used to ground the motor and driver must be as thick and short
as possible so that no potential difference is generated.
y
Choose a large, thick and uniformly conductive surface for the grounding
point.
y
Install the motor to the grounded metal plate.

The driver uses parts that are sensitive to electrostatic charge. Take
measures against static electricity since static electricity may cause
the driver to malfunction or suffer damage.
