Siemens S120 Commissioning the cooling circuits, Checks for commissioning in a current-free state

Commissioning

9.2 Procedure

Commissioning the cooling circuits

Before the cooling circuits are charged, they must be rinsed with the cooling medium.

NOTICE

The maximum permissible pressure in the cooling circuit (see "Technical features") must not be exceeded.

Checks for commissioning in a current-free state

Cooling circuit

Make sure that the cooling circuit and the coolant meet the requirements outlined in the "Cooling" section of the 1FW6 Configuration Manual (1FW6 CM) for built-in torque motors, and that the cooling circuit is functioning correctly.

Mechanical components

●The axis must be able to rotate freely throughout the entire rotating range.

●In the case of motors connected in parallel, motor installation and the installation positions of the stator and rotor must comply with the installation drawings and specifications in the 1FW6 CM.

●A "vertical axis (large imbalance)" requires a fully functional counterweight (this may or may not be provided).

●If a brake is provided, it must be controlled correctly.

●If there is a limit on the travel range, mechanical limit stops must be present and permanently attached at both ends of the rotating range.

●Moving cables must be correctly laid in a tow chain.

Measuring system

●Incremental measuring system: Grid spacing _ _ _ _ _ _ _inc./rotation Number of zero marks _ _ _ _ _ _

OR

●Absolute (EnDat) measuring system: Grid spacing _ _ _ _ _ _ _ inc./rotation

●Determine positive drive direction of rotation:

The positive counting direction of the measuring system must be determined. It may be necessary to invert the direction of rotation.
