What is maximum cable length between Piezo motor and the driver?

How long can the cables between Piezo motor and driver be?

  • Dear Dean,
    We have tested 50m motor cable. The conductors should not be too thin, or else there may be considerable voltage drops in the long cable, especially for big motors at high speed. The sensor cable may be rather susceptible to voltage drop on the power line. An external power supply with somewhat higher voltage to allow voltage drop in the cable could be an option. Furthermore, differential sensor signals may be needed and the sensor datasheet should be consulted.
    Best regards,
