Parameter Descriptions
CALIBRATN STATUS
PREF: 158.13
Default: 0
Range: see below
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
0 : NOT REQUIRED
1 : DRIVE NOT STOP'D
2 : MOTOR NOT STOP'D
3 : ENDAT FAULT
4 : CAL IN PROGRESS
5 : ID PSN IN PRGRSS
6 : COMPLETED
7 : CALIBRATION LOST
8 : CALIBRATN FAILED
REV COUNT
PREF: 158.15
Default: 0
Range: —.
This counts the number of turns of the encoder input. 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.
