GD350A series high-performance multifunction VFD
-6-
recommended that the VFD be used at the altitude higher than 5000m.
Check whether the humidity of the actual usage site exceeds 90% and condensation occurs.
If yes, take additional protective measures.
Check whether the actual use site may be exposed to direct sunlight or may have the chance
of ingress of foreign objects. If yes, take additional protective measures.
Check whether there is dust, explosive gas, or flammable gas in the actual use site. If yes,
take additional protective measures.
2.5 Installation confirmation
Check the following after the VFD installation:
Check whether the load ranges of the input power cable and motor cable meet the actual
load requirement.
Check whether correct accessories are selected for the VFD, the accessories are correctly
and properly installed, and the installation cables meet the requirements of all components
(including the reactor, input filter, output reactor, output filter, DC reactor, braking unit and
braking resistor).
Check whether the VFD is installed on non-flammable materials and the heat-radiating
accessories (such as the reactor) are away from flammable materials.
Check whether all control cables and power cables are run separately and the routing
complies with EMC requirement.
Check whether all grounding systems are properly grounded according to the requirements
of the VFD.
Check whether all the installation clearances of the VFD meet the requirements in the
operation manual.
Check whether the installation conforms to the instructions in the operation manual. It is
recommended that the VFD be installed uprightly.
Check whether the external connection terminals of the VFD are tightly fastened and the
torque is appropriate.
Check whether there are screws, cables, or other conductive items left in the VFD. If yes, get
them out.
2.6 Basic commissioning
Complete the basic commissioning as follows before the actual use of the VFD:
According to the actual motor parameters, select the motor type, set motor parameters, and
select the VFD control mode.
Autotune. If possible, de-couple the VFD from the motor load to start dynamic autotuning. If
the VFD cannot be de-coupled from the load, perform static autotuning.
Adjust the ACC/DEC time according to the actual work condition of the load.
Perform device commissioning by means of jogging and check whether the motor rotational
