For the "Safe cam track" monitoring function there is a different status
between the NCK and drive for cams SN19 to SN24. The actual status
image of the NCK (result list 6) is output as supplementary info %3
(comparison value NCK) and the actual status image from the drive is
output as %4.
Supplementary infos %3 and %4 are also saved in drive parameters
r9738[0] (NCK) and r9738[1] (drive).
Remedy
Result list 6. Check the tolerance of the cams, evaluate the fault code
in drive parameter r9738[0,1].

For the "Safe cam track" monitoring function there is a different status
between the NCK and drive for cams SN25 to SN30. The actual status
image of the NCK (result list 7) is output as supplementary info %3
(comparison value NCK) and the actual status image from the drive is
output as %4.
Supplementary infos %3 and %4 are also saved in drive parameters
r9739[0] (NCK) and r9739[1] (drive).
Remedy
Result list 7. Check the tolerance of the cams, evaluate the fault code
in drive parameter r9739[0,1].

associated drive value.
Remedy

drive value The filtering must be deactivated if, as a result of the con-
figured acceleration levels or velocities, CDC errors do occur.
Remedy
Increase MD36947 $MA_SAFE_VELO_X_HYSTERESIS. Set
MD36945 $MA_SAFE_VELO_X_FILTER_TIME higher
