General Precautions Regarding DYNASERV
•
Never install the DYNASERV motor in reverse, i.e. fixing the rotor of the motor and
making the stator rotate.
•
When removing the drive-side panel to replace consumables, etc., be sure to turn the
power OFF before doing so. It is dangerous to touch the high-voltage parts inside the
unit.
•
The motor rotates at a high velocity and torque. Take the rotation radius into
consideration during operations with load attached, and be sure to take precautions to
avoid the risk of bodily injury or equipment damage.
•
Be sure to ground the ground terminal to the earth.
•
When mounting a load on the motor rotor, be sure to leave a clearance between the
load and the upper surface of the motor of 1mm or more in order to maintain the
intended precision.
•
Never press an object into the hollow hole or apply force to it. When you lead an object
through the hollow hole, be sure to secure a clearance of 1 mm or more on both sides.
If force is applied to the hollow hole in the DM
motor, the internal encoder may be
damaged. The DR
motor has a hollow hole in its casting, so take the dimensional
allowance into consideration and use it with sufficient margins for both sizes and
shapes.
•
Do not subject the motor to strong force, impact or magnetic field. Please be aware
that the DR
motor is equipped with a built-in magnetic resolver.
•
Be sure the mounting screws of a load never reach or exceed the effective screw
depth of the motor unit. Depending on the model used, the functions may be impaired
and failure may occur if screws reach or exceed the effective screw depth.
•
If you use the screw holes located above and below the box of the DrvPIII drive, be
certain the tips of the screws penetrate no more than 8 mm for the 500 mV and 2 kW
classes, or 6 mm for the 4 kW class, below the drive's surface. If this precaution is not
observed, it may cause an electric shock, short circuit and/or damage to the motor.
