2. LINEAR SERVO MOTOR
POINT
To execute the high accuracy positioning, ensure as much rigidity of machine
as possible and make the machine resonance point higher.
Make the moving parts as light as possible and make the base parts heavier
and sturdier.
As the operation and accuracy of machine could have an adverse effect,
design it in order to make the thrust center of the linear servo motor closer to
a moving body's gravity center.
When the mounting rigidity of the linear encoder is not enough, machine
vibration, etc. affect the feedback signal, and the desired performance may
not be satisfied. As it is also the same case when the linear encoder is
susceptible to electric noise, set up and mount the linear encoder so that it is
affected by as little vibration and noise as possible.
Establish the structure to sustain the high-speed and the high acceleration
and deceleration.
2.1.3 Instructions on installation operation
WARNING
Under the packaged condition (cardboard) delivered from our company, the
magnet on the secondary side does not have a serious effect on the outside.
Before mounting to the machine, however, magnetic bodies (including tools) must
be kept away from the secondary side (magnetic). The secondary side (magnetic)
can have as double suction power as mounted normally, which may cause a
serious injury. To avoid this, pay full attention to the ambience of workplace.
Magnetic body such as iron
Secondary side (magnet)
Magnetic suction power: Max. 5 ton
The permanent magnet on the secondary side makes the magnetic bodies
generate suction, which may cause troubles such as having hands pinched, etc.
For the installation of the linear servo motor and the work around it, be sure to use
nonmagnetic tools. These are required for the improvement of workability and
safety ensuring. Use special caution with mounting the primary side (coil) after the
secondary side (magnet) has mounted. Use the screw which strength must be a
high tensile strength steel level of SCM435 for its material and the lower yield
point 900 [N/mm2] or more. (Example) Explosion-proof beryllium copper alloy
safety tools: Manufactured by NGK Insulators, Ltd.
CAUTION
Do not install the servo motor, linear servo motor and regenerative brake resister
on or near combustibles. Otherwise a fire may cause.
Securely attach the linear servo motor to the machine. If attach insecurely, it may
come off during operation.
Install the servo amplifier in a load-bearing place in accordance with the
Instruction Manual.
