When you receive the product, verify the model name and code of the product’s main unit, whether all the
standard accessories are included, and that the combination of a motor and a driver is correct before you begin
installation and wiring.
2.1 Installation of the Motor
The motor part can be installed and used in either a horizontal or a vertical position. However, if installed in a
wrong way or position, the life of the motor may be shortened or the motor may fail. Always follow the
instructions explained below.
(1) Installation Position
The motor part is designed based on the assumption that it is used indoors. Therefore, choose the location of
installation so that it satisfies the following conditions:
! It should be indoors and not in a place where it can be exposed to corrosive and/or volatile gases.
! The ambient air temperature should be from 0 to 45 °C.
! There should not be too much dust or particles, the ventilation should be good, and the humidity should
be low.
Note: The DYNASERV is not drip- or water (oil)-proof. If it is used in such an environment, a proper drip- or
water (oil)-proof cover should be applied.
(2) Mechanical Installation
! When installing a load on the rotor of the motor, make sure to secure a clearance of 1 mm or more
between the upper surface of the motor and the installed part in order to maintain the surface accuracy.
! The clamping torque of the screws used to install the rotor and stator of the motor should be equal to or
less than the value indicated below.
! The surface flatness where the motor is fixed should be 0.01 mm or less.
