Before switching on
Check:
¯
The oil level of the gearbox after previous long−term storage!
¯
That the drive does not show any visible signs of damage.
¯
Is the mechanical fixing o.k.?
¯
Has the electrical connection been implemented correctly?
¯
Is the assignment of the drive function − machine function correct?
¯
Is the direction of rotation of the drive shaft correct?

Stop!
At input speeds below 200 rpm the amount of lubricant may need to be
increased. Consultation with Lenze is required.

Initial commissioning
In order to ensure trouble−free operation, carry out checks during initial commissioning.
When
Check
At initial start−up
Rotating direction of the drive shaft (Fig. 17)
Continuously
Monitor geared motor with regard to noticeable noise, vibrations,
and changes
After 3 hours under rated load
Measure housing temperature (Tab. 9) at the hottest point. The value
measured at the same time serves as a reference value for later
measurements. If necessary, implement required measures if
temperatures are rising too high,
Fastening elements, locking screws, and covers
Leakages: small quantities of escaping lubricant
After the first day
Check oil level,
