1.2.3.3.2.4.2 Check encoder system
Performs a diagnostic test of the encoder system. One rotation of the currently selected encoder will be done
in the open-loop field control mode. The obtained data will be used to compute a distance map over a full
revolution. This is helpful to detect distance variations and hence axial runout of the encoder ring or eccentric
motion.
This visualisation helps you detect possible problems with the mounting of the encoder ring:
Case 1: Some axial runout detected, the ring is too close. This can lead to a collision with the read head.
Case 2: Axial runout present, check the quality of the encoder ring assembly.
Case 3: No Axial runout detected, this should be the goal.
1.2.3.3.2.4.3 Check encoder errors
This command establishes a direct communication with the encoder chip and the Multiturn counter (if
configured). Error registers are read and displayed:
Name Description/remedy
Startup error Encoder initialization error. Power cycle the drive, connect the multiturn
battery (if multiturn is used).
Signal error: clipping (nonius
track)
A magnetic ring is too close to the encoder chip. Check the mechanical
assembly.
Signal error: poor level
(nonius track)
A magnetic ring is too far from the encoder chip. Check the mechanical
assembly.
Signal error: clipping (master
track)
A magnetic ring is too close to the encoder chip. Check the mechanical
assembly.
Signal error: poor level
(master track)
A magnetic ring is too far from the encoder chip. Check the mechanical
assembly.
Excessive signal frequency for
internal 12 Bit converter
Encoder maximum speed is exceeded.
