When installing a new Sinumerik or Simodrive unit, there is a specific set of checks that you should go through to make sure that everything is functioning properly. Siemens issues the following check list, and we always recommend that people go through the list to avoid any possible issues with a new installation.
The following check list should help you to simply commission the components
we have supplied and guarantee a high availability when used in conjunction
with your product or equipment.
- Observe all of the ESD measures when handling components.
- Tighten–up all bolts and screws to the specified torque. Pay special attention to the DC link bolt connections (1.8 Nm tightening torque).
- Correctly insert all connectors and lock/screw into place.
- Screw the control components into the power module.
- Observe the power–on sequence in the Planning Guide.
- If the unit is frequently powered–down and up, the DC link charge circuit is locked out. The DC link can only be charged again after it has cooled down for several minutes with the supply off.
- Are there line supply/motor contactors connected to the drive converter? These are only switched in a no–current condition.
- Ground all components and connect all of the shields. Connection X131 is grounded.
- Observe the load capability of the central power supply.
- Only discharge the unit at the DC link buses through a minimum of 10Ω
- In operation, units with hard disks may only be stressed with a of max. 1 g (read/write error; defective).
- Use the correct software for the particular unit.
- Are OEM components (ISA–/PCMCIA card) used? Their current drain must lie within the specified values.
- CRT monitors may not be subject to magnetic fields (e.g. power supply unit coils).
- When commissioning and fault finding, always proceed in a modular step–by–step fashion.This means: First commission the central controller and line supply module, then connect–up and commission the components one after another.
- The units are designed for the specified mechanical, climatic and electrical ambient conditions. None of the limit values may be exceeded, neither in operation nor during transport. Please pay specific attention to the following:
– line supply conditions
– pollutants
– damaging gases
– climatic ambient conditions
– storage/transport
– shock stressing
– vibration stressing
– ambient temperature
