5.1.2 Motor Component

Insulation measurement
Measure the insulation resistance of the winding with a
commercially available measuring tool
(for example, megger) between all winding parts and
between the winding and the enclosure.
Measured value
>50 MΩ
<5 MΩ
approximately 50 MΩ
Table 5.1 Insulation Measurement Values

5.1.3 Gear Unit Component

•
Oil
Change the oil in the gear unit if the storage
period exceeds 5 years or the temperatures were
harsh throughout a shorter storage period. For
detailed instructions and oil recommendations
see chapter 6.4.3 Oil Volume.
•
Shaft seals
Lubricate the hollow shaft seal with grease if the
storage period exceeds 2 years. When changing
the oil, the function of the shaft seals between
the motor and gear unit as well as on the output
shaft must also be checked. The shaft seals must
be replaced if any change in shape, colour,
hardness or sealing effect is detected.

5.2 Commissioning Procedure

1. Remove the protective films.
2. Disconnect the mechanical connection to the
driven machine as far as possible and examine
the direction of rotation in the no-load state.
3. Remove the feather keys or secure them in such
a way that they cannot be ejected.
4. Ensure that the current draw in the loaded
condition does not exceed the rated current
indicated on the nameplate for any length of
time.
5. After first commissioning, observe the
OneGearDrive for at least 1 hour to detect any
unusual heat or noise.
