Before initial switch-on
That the drive does not show any visible signs of damage.
•
Is the mechanical fixing o.k.?
•
Is the electrical connection ok?
•
Are all rotating parts and surfaces that may become hot protected against contact?
•
Is the featherkey radially secured during the test run without output elements?
•
Have all screwed connections of the mechanical and electrical parts been tightened?
•
Is it ensured that the cooling air can be freely supplied and discharged?
•
Has the PE conductor been connected correctly?
•
Are the protective devices against overheating (e.g. thermal sensor evaluation) working?
•
Has the inverter been parameterized suitably for the motor?
•
Is the phase sequence of the motor connection correct?
•
Is the contact of good electrical conductivity if a PE connection on the motor housing is
•
used?
After a long period of downtime or after overhauling the motor, check the insulation
resistance prior to initial switch-on, as condensation may have formed.
If the values measured are ≤1 kΩ per volt of the rated voltage, the insulation resistance is
•
inadequate and no voltage is to be applied.
Dry the winding until the insulation resistance is >1 kΩ per volt of the rated voltage.
