7 Commission ing and operation
Stop!
The drive may only be commissioned by skilled personnel!
7.1 Before switching on
Please check:
• That the drive does not show any visible signs of damage.
• Is the mechanical fixing o.k.?
• Has the electrical connection been carried out properly?
• Are all rotating parts and surfaces that may become hot protected against
contact?
• If the oil level of the drive was increased for the purpose of longer storage, it now
has to be reduced to the quantity intended for the mounting position ( 22).
• For gearboxes with ventilation:
– Has the transport locking device been removed?
7.2 During operation
During operation, check the drive periodically and take special care of:
• changes compared to normal operation, like
– unusual noise, stronger vibrations or increased temperatures,
– leakages,
– loose fixing elements,
– the condition of the electrical cables.
• In the event of faults:
– shut down the drive,
– check the troubleshooting table.
If the fault cannot be remedied, please contact the Lenze customer service.
7.3 Clutches at the GKK gearbox
The clutch (jaw coupling) is designed for switching under load. It is arranged in the
gearbox between first and second gearbox stage. Disengaging causes an interruption
of the power flow between motor and driven shaft so that the driven shaft can be freely
rotated.
