Preface
Note
● This drive is a general industrial automation product, and is not designed for use in
machinery or systems on which lives depend.
● Wiring, operation, maintenance and inspection of the product can only be conducted by a
qualified person.
● When selecting the tightening torque of the screw, consider the strength of the screw and
material of the installation part. Select a proper value while the screw is fixed solidly and the
installation part will not be damaged.
● Install a correct safety device when this product is to be used on machinery which may
cause a serious accident or loss due to trips of the product.
● Contact Inovance when this product is to be used on special applications such as atomic
energy control, aerospace equipment, transport equipment, medical apparatus, safety
devices and other equipment that require high cleanliness.
● Although this product has passed all QC testing, it may react unexpectedly due to trips
arising from ambient noise, static interference, input power supply, wiring, optional parts,
and so on. Take mechanical safety measures into full consideration to ensure safety in the
application site where all possible actions of the equipment occur.
● When the motor shaft runs without being grounded, based on the actual mechanical and
installation conditions, the motor bearing may suffer from electric corrosion or large noise.
Please confirm it yourself.
● Trips of this product may cause rising smoke. Pay special attention to such conditions when
the product is to be used in a purification workshop and similar environments.
● Note that the chip resistor disconnection or poor contact condition may occur due to a
sulfuration reaction if the product is to be used in an environment with high-density sulphur
or sulfuretted gas.
● Pay attention to the input voltage to the product. Inputting a voltage far larger than the rated
voltage may cause damage to the internal components, thus resulting in smoke or a fire.
● The end user decides whether the servo drive matches the structure, size, service life,
features, specification change of the equipment (to which the servo drive is to be installed)
and its parts, and whether it complies with local laws and regulations.
● Note that use of this product beyond its specifications can be not guaranteed.
● This product is subject to change of certain components as we are dedicated to continuous
improvement of the product.
