    If a manual is missing or problems occur with downloading:  Contact our customer service department (p. 35). Downloading manuals 1. Open the website www.pi.ws. 2. Search the website for the product number (e.g., N-472) or the product family (e.g., PiezoMike).

  • Page 9: Safety

    The intended use of the N-472 is only possible in conjunction with a suitable controller (p. 12), which is available from PI. The controller is not included in the scope of delivery of the N-472. The controller must provide the required operating voltages. It must also be able to read out and process the signals from the position sensors so that the servo control system can function properly.

  • Page 10: Organizational Measures

    Measures for Handling Vacuum­Compatible Products When handling the vacuum version of the linear actuator, attention must be paid to appropriate cleanliness. At PI, all parts are cleaned before assembly. During assembly and measurement, powder-free gloves are worn. Afterwards, the linear actuator is cleaned once again by wiping and shrink-wrapped twice in vacuum-compatible film.

  • Page 29: Startup And Operation

    Operating voltages that are too high or incorrectly connected can cause damage to the N-472.  Operate the N-472 only with controllers/drivers and original accessories from PI.  Do not exceed the operating voltage range (p. 40) for which the N-472 is specified.
  • Page 30 Operating frequency too high! An excessively high operating frequency can cause damage to the N-472.  Operate the N-472 only with controllers/drivers and original accessories from PI.  Do not exceed the operating frequency range (p. 40) specified for the N-472.
  • Page 31 6 Startup and Operation NOTICE Increased wear due to friction! Increased friction on the contact surface between the ball tip and the movable part of the mechanical mounting increases wear.  Make sure that the contact surface of the mechanical mounting has a roughness of R <0.1 µm and a hardness of at least 500 HV (corresponds to hardened steel).
