     - Use the **''PZINFO''** command as described above to see if the high voltage is still low on the original problem card/axis.  If not, check the other one.  If the problem stays with the card then the problem is likely with the card.  If the problem moves with the actuator then the problem is likely with the actuator.     - Use the **''PZINFO''** command as described above to see if the high voltage is still low on the original problem card/axis.  If not, check the other one.  If the problem stays with the card then the problem is likely with the card.  If the problem moves with the actuator then the problem is likely with the actuator.
