Before initial switch-on

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 a protection against contact provided in front of rotating parts and in front of surfaces
that can get hot?
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.

Functional test

After commissioning, check all individual functions of the drive:
Rotating direction in decoupled state
Torque behavior and current consumption
Function of the feedback system
Brake function
During operation, carry out inspections on a regular basis. Pay special attention to:
Unusual noises
Irregular running
Increased vibration
Loose fixing elements
Condition of electrical cables
Speed variations
Deposits on the drive and in the cooling channels
