Description:
    Macros to control a piezo cristal connected via serial line. Version 2.0
Documentation:
    DESCRIPTION
    This macro file allows to connect a piezo to a pseudo motor in SPEC. Derived from dac.mac
    History:
    2.0 31.3.2000 Multiple channels per controller handled properly.


    EXAMPLE
    mv pzo1 5.3
    Value of 5.3 (unit um) set in piezo pzo1.
    ascan pzo2 0 10 10 1
    (scan pzo2 from 0 to 10 in 10 steps and count for 1 second)
    a2scan pzo1 0 20 opti 0 5 10 1
    (scan the optical table stepper motor from 0 to 5 degrees and scan at the same time the pzo1 from 0 to 20 micr.)


    DEPENDENCIES
    To use a piezo as a motor the following conditions have to be fulfilled:
    • The file piezo_gpib.mac has to be read in done by: startup s. (this file needs: pseudo.mac , stchanges.mac)
    • the piezo motors have to be configured done by: SPECADM (Controller NONE, mnemonic as in startupscript)
    • setup the piezos ( with pzosetup ) done by: startup s.
