Remedy Please inform the authorized personnel/service department. Check the entry in
machine data MD 1331: $MD_SAFE_VELO_LIMIT[n] (limit values for safely-
reduced speed) correct, if necessary, and carry-out a power on.
Program continuation Power-down the control and power-up again.

Axis %1 drive %2 parameterization of cam position invalid
Parameter %1 = NC axis number
%2 = drive number
Explanation At least one of the parameterized cams enabled via MD 1301:
$MD_SAFE_FUNCTION_ENABLE (enable safety-relevant functions) has failed
to comply with the rule that cam positions may not be located within the
tolerance range around the modulo position.
The valid tolerance range is:
•

Remedy Please inform the authorized personnel/service department.
Check/correct parameter settings of cam positions in
MD 1336: $MD_SAFE_CAM_POS_PLUS (plus cam position for safe cams) or
MD 1337: $MD_SAFE_CAM_POS_MINUS (minus cam position for safe cams)
and carry-out power on.
MD 1305: Check $MD_SAFE_MODULO_RANGE (for rotary axes, the actual
value range for SN).
Program continuation Power-down the control and power-up again.

Axis %1, drive %2 Invalid modulo value parameters for SN
Parameter %1 = NC axis number
%2 = drive number
Explanation The cam modulo range parameterized in $MD_SAFE_MODULO_RANGE (for
rotary axes, the actual value range for SN ) for a rotary axis has failed to

for inactive cam synchronization (MD 1301 bit 7 = 0):
lower modulo value + POS_TOL ≤
upper modulo value - POS_TOL
for active cam synchronization (MD 1301 bit 7 = 1):
lower modulo value + POS_TOL
upper modulo value - POS_TOL - CAM_TOL >
Explanations:
POS_TOL: Actual value tolerance (MD 1342: $MD_SAFE_POS_TOL
(tolerance, crosswise actual value comparison))
CAM_TOL: Cam tolerance (MD 1340: $MD_SAFE_CAM_TOL
(tolerance for safe cams))
lower/upper modulo values:
