  • Page 7: Basic Safety Notices

    Only original parts from HIWIN may be used as spare parts and accessories. Spare parts and accessories not supplied by HIWIN are not tested for operation with HIWIN MAGIC distance measuring systems and may compromise operational safety and reliability.

  • Page 8: Safety Information On Handling Current-Carrying, Live Products

    Assembly Instructions HIWIN MAGIC Distance Measuring System Basic safety notices NOTE The measuring scale of the magnetic distance measuring systems must not be subjected to any strong magnetic fields (keep it away from permanent magnets of linear motor axes!). Strong shocks (e.g. hammer blows) can also damage the magnetization of the measuring scale.

  • Page 9: Product Descriptions

    Product descriptions Product descriptions The magnetic distance measuring systems of the HIWIN MAGIC series are optimised for measuring the distances travelled in linear movements and particularly on linear motor axes. They are particularly suitable for use in harsh environmental condi- tions and are resistant to oil, dirt, vibrations and shocks.

  • Page 10: Connection

    Fig. 3.6 Cable with coupling (optional) 3.4 Reference switch The MAGIC encoder delivers index signals at a distance of 1 mm. For the definition of a reference point, a reference switch (“cam switch”) is required. For this purpose, HIWIN offers an inductive proximity switch (see Fig. 3.7).

  • Page 11: Scope Of Delivery

    HIWIN MAGIC Distance Measuring System Product descriptions 3.5 Scope of delivery Depending on customer requirements, the distance measuring systems MAGIC and MAGIC-PG are offered in different forms and with different scope. Individual components can be supplied to retrofit existing linear guideway systems.

    It is advisable to use a feeler gauge to set the correct distance. Make sure that the minimum cable bending radius of 40 mm is not underrun. 4.2 Assembly of the HIWIN MAGIC-PG – HG and QH series 4.2.1 Assembly of the profile rails Fit the profile rails as described in the assembly instructions for the linear guideways.

NOTE Using the assembly aid provided in order to prevent balls from falling out. Clean the groove thoroughly with alcohol or isopropyl alcohol so that it is free of grease and dust.
  • Page 15 Remove the end seal [3] by loosening the screws [7]. Adjust the distance between the cover strip [1] and the MAGIC-PG encoder [4] to 0.2 ±0.1 mm. It is recommended to use a feeler gauge to set the correct distance.
  • Page 16 Do not disassemble the recirculation unit [7]! Assembly steps: On the side where the MAGIC-PG encoder [6] should be replaced, remove the end seal [5] by loosening the screws [4]. Remove the defective MAGIC-PG encoder [6] by loosening the screws [9].
