Description of the motor 2.2 Technical features

2.1.3Applications

In conjunction with the SINAMICS S120 drive system (booksize or blocksize format), the built-in torque motors can be used as a direct drive for the following machine applications:

●Rotary indexing machines, rotary tables, swivel axes

●Rotary axes (A, B, C axes in 5-axes machine tools)

●Rotary tables, rotary indexing machines, sub-machine assemblies

●Turret indexing and drum indexing for single-spindle and multi-spindle machines

●Dynamic tool magazines

●Rotating spindles in milling machines

●Roller and cylinder drives

●Infeed and handling axes

WARNING

The motors cannot be operated directly on the supply system, but may only be operated with a suitable drive system.

Note

Note that when 1FW6 direct motors (torque motors) are used in fork heads for machine tools or robots, a license for US patent US5584621 and the associated international patent protection may be required.
