Lenze G7 Series - Commissioning; Before Initial Switch-On; Functional Test

Commissioning
Before inial switch-on
•
That the drive does not show any visible signs of damage.
•
Is the mechanical xing o.k.?
•
Is the electrical connecon ok?
•
Are all rotang 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 connecons of the mechanical and electrical parts been ghtened?
•
Is it ensured that the cooling air can be freely supplied and discharged?
•
Has the PE conductor been connected correctly?
•
Are the protecve devices against overheang (e.g. thermal sensor evaluaon) working?
•
Has the inverter been parameterized suitably for the motor?
•
Is the phase sequence of the motor connecon correct?
•
Is a protecon against contact provided in front of rotang parts and in front of surfaces that can get hot?
•
Is the contact of good electrical conducvity if a PE connecon on the motor housing is used?
Aer a long period of downme or aer overhauling the motor, check the insulaon resistance prior to
inial switch-on, as condensaon may have formed.
•
If the values measured are ≤1 kΩ per volt of the rated voltage, the insulaon resistance is inadequate and
no voltage is to be applied.
•
Dry the winding unl the insulaon resistance is >1 kΩ per volt of the rated voltage.
Funconal test
Aer commissioning, check all individual funcons of the drive:
•
Rotang direcon in decoupled state
•
Torque behavior and current consumpon
•
Funcon of the feedback system
•
Brake funcon
During operaon, carry out inspecons on a regular basis. Pay special aenon to:
•
Unusual noises
•
Irregular running
•
Increased vibraon
•
Loose xing elements
•
Condion of electrical cables
•
Speed variaons
•
Deposits on the drive and in the cooling channels
