2.  *Ambient temperature 25°C, heat dissipation by natural convection, without heat sink attached.
3.  Specifications tolerance – inductance +/-30%, all others +/-10% (for motor parameters).
4.  Peak force and current – 1 second duration
5.  ** Depend on encoder resolution
6.  *** Specific accuracy, straightness and flatness requirement, contact PBA for more information.
7.  For customized stroke length, contact PBA.
