•
By mechanical adjustment, change the position of the
IC with respect to the code disc/ linear scale until
AI_SCALES = ’1.00’
AI_PHASES = ’0 deg e’
•
When the ideal position is found, stop ’Reading...’ and
disable dynamic phase and dynamic scale adjustment
by setting
AI_S_SEL = ’Disabled’ [ = 0x00]
AI_P_SEL = ’Disabled’ [ = 0x00]
Then perform automatic electrical adjustment.
PROCEDURE FOR AUTOMATIC ELECTRICAL ADJUSTMENT
iC-PZ is designed for high resolution position measure-
ment without the need for precise mechanical alignment
of the IC to the code disc or linear scale. Highly au-
tomated production processes can only provide place-
ment with limited accuracy. To correct the errors re-
sulting from mechanical misplacement, iC-PZ provides
numerous automatic calibration functions. The follow-
ing procedure is proposed for the automatic electrical
adjustment:
Filter configuration
•
In tab ’System Config’ set filter parameters to its de-
fault values
IPO_FILT1 = ’110’ [ = 0x6E]
IPO_FILT2 = 4 [ = 0x04]
to allow stable operation with systems that are not yet
electrically adjusted.
