Mechanical And Electrical Check - Siemens SIMOTICS DP Operating Instructions Manual

Commissioning
7.1 Measures before commissioning
Once the system has been correctly installed, you should check the following prior to
commissioning:
• The machine is undamaged.
• The machine has been properly installed and aligned.
• The output transmission elements are set correctly for their type,
e.g. alignment and balancing of couplings, belt forces in the case of a belt drive, tooth forces
and tooth-flank backlash in the case of geared output, radial and axial clearance in the case
of coupled shafts.
• All fixing screws, connection elements, and electrical connections have been tightened to
the specified tightening torques.
• The operating conditions match the data provided in accordance with the technical
documentation, such as degree of protection, ambient temperature, etc.
• Moving parts, for example the coupling, move freely.
• All touch protection measures for both moving and live parts have been implemented.
• Screwed-in lifting eyes are removed after installation or secured to prevent them from
becoming loose.
• Before commissioning, attach the covers to guarantee the correct air guidance.
• Ensure that all condensation drain holes are always located at the lowest part of the machine.
Second shaft end
If the second shaft end is not used:
• Carefully secure the feather key to prevent it from being thrown out, and for balancing type
"H" (standard type), ensure its weight is reduced to approximately 60 % of the original value.
• Using covers, carefully secure the unused shaft end so that it cannot be touched.
Risk of losing the IP degree of protection as a result of damaged shaft sealing rings
This can result in death, serious injury, or material damage.
• Replace damaged components immediately.
7.1.2

Mechanical and electrical check

Danger to life as a result of voltage at the motor terminals when the rotor is rotating
There is always a magnetic flux in the motor due to the permanent magnets in the rotor. With
each rotation of the rotor, a voltage occurs at the motor terminals. As a result of this, there is also
a voltage at the converter output terminals via the connecting cable. Contact with them can
cause death, serious injury or material damage.
• When working on the drive system, you must prevent any rotational movement of the motor
shaft.
