Detailed functional description
Design of the linear direct axis
The linear direct axes of the LDx product series (illustration corresponds to linear module LDN) comprise a motor slide with an integrated primary part and measuring system. The secondary part consists of permanent magnets and is integrated into the axis profile of the linear axis.
- 1 Axis profile: (e.g., steel guide rail or aluminum profile)
- 2 Permanent magnets with dirt cover
Modular transducer system
The linear module (similar to illustration) is available with four different stroke measuring systems. The incremental stroke measuring system has a 1Vss interface. Absolute path measuring systems are optionally available with HIPERFACE®, SSI, or DRIVE-CLiQ interfaces.
- 1 Measuring system reading head: Fixed on the motor slide
- 2 Measuring system tape measure: Fixed on the aluminum profile
Pneumatic holding brake
Optionally, the linear module (similar to illustration) is equipped with a pneumatically actuated holding brake. Its function is activated in a non-ventilated state and is used to maintain the position of the linear axis in a currentless state.
- 1 Holding brake: Operated pneumatically
Drag chain
Matching cable tracks are available as accessories for the linear axes (similar to illustration). These are adapted to the respective effective stroke, supplied with mounting material, and if necessary, pre-assembled.
- 1 Drag chain
