Parameter Descriptions
REV COUNT
This counts the number of turns of the motor shaft. It will normally start from zero on power-up. If a multi-turn Endat encoder
is fitted, REV COUNT will be made to match the multi turn encoder rev count. However, it will continue to count beyond the
Endat range of 0 to 4095 revs. It will count to the limits of a 32 bit number, but the lower 12 bits will be equal to the Endat rev
count.
CALIBRATN STATUS
If a sincos absolute Endat encoder is fitted (single-turn or multi-turn), the software will attempt to match the slow absolute
position (Endat) information to the fast analog feedback information, to obtain a fast absolute position feedback. This will
normally be done on power-up. If the encoder is wired correctly and working correctly, these should match. The
CALIBRATN STATUS diagnostic will then display COMPLETED. If the encoder is not an absolute type, the diagnostic will
show NOT REQUIRED. If calibration fails, this diagnostic will indicate where the problem may lie. Refer to CAL FAIL
RETRY.
Enumerated Value : Type
Note that if an absolute endat encoder is used, the encoder MUST be wired exactly as specified. If not, it will fail to calibrate
the absolute position and an error will result when the drive is started. This could be CALIBRATION FAILED or CAL
WARNING.
