The intended use of the N-472 is only possible in conjunction with a suitable controller (p. 13), 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.
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.

(e.g., linear actuator type, serial number, date of manufacture, hardware version). When switched on or rebooted, controllers from PI read the data from the ID chip. For more information on the ID chip recognition, see the manual of the controller used.
INFORMATION 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 is then shrink-wrapped twice in vacuum-compatible film.

NOTICE Damage from unsuitable cables! Unsuitable cables can cause damage to the controller. Only use cables from PI to connect the N-472 to the controller. NOTICE Dirt, condensation, lubricants! Dirt, condensation and inappropriately applied lubricant render the drive inoperable.
5 Installation NOTICE Damage to the finethread screw from contact with hard objects! Contact with hard objects can damage the thread of the fine-thread screw. A damaged thread can lead to the failure of the linear actuator. Prevent the fine-thread screw from coming into contact with hard objects. NOTICE Damage from overtightening the mounting nut! Overtightening the mounting nut can damage the linear actuator.

Operating voltages that are too high or incorrectly connected can cause damage to the N-472. Only operate the N-472 with controllers/drivers and original accessories from PI. Do not exceed the operating voltage range (p. 41) for which the N-472 is specified.
Page 32
An operating frequency that is too high can cause damage to the N-472. Only operate the N-472 with controllers/drivers and original accessories from PI. Do not exceed the operating frequency range (p. 41) for which the N-472 is specified.
Page 33
6 StartUp and Operation NOTICE Increased wear due to friction! Increased friction on the contact surface between the ball tip and the moving part of the mechanical mounting increases wear. Make sure that the contact surface of the mechanical mounting has a roughness of <0.1 µm and a hardness of at least 500 HV (corresponds to hardened steel).
Observe further information on the operating conditions in the "Technical Data" section (p. 39). The N-472 is started up with the E-871 controller (p. 13) from PI. Operating Parameters If you use the software enclosed with the E-871 controller, the operating parameters can be loaded from the PIStages2.dat stage database.
