SIMODRIVE alarms
301706 Axis %1 drive %2 parameterization of cam position invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: At least one of the parameterized cams enabled via MD 1301: $MD_SAFE_FUNCTION_ENABLE
(safe functions enable) does not comply with the rule stating that cam positions are not allowed to be
within the tolerance range around the modulo position.
The valid tolerance range is:
With inactive cam synchronization (MD 1301 bit 7 = 0):
Lower modulo value + POS_TOL <= cam position
Upper modulo value - POS_TOL > cam position
With active cam synchronization (MD 1301 bit 7 = 1):
Lower modulo value + POS_TOL <= cam position
Upper modulo value - POS_TOL - CAM_TOL > cam position
Explanations:
- POS_TOL: Actual value tolerance (MD 1342: $MD_SAFE_POS_TOL (actual value tolerance cross-
comparison))
- CAM_TOL: Cam tolerance (MD 1340: $MD_SAFE_CAM_TOL (tolerance for safe cams))
- Upper/lower modulo value: is determined by MD 1305: $MD_SAFE_MODULO_RANGE (actual
value range for safe cam with rotary axes)
Reaction: Mode group not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department.
Check parameterization of the cam positions in
- Modify MD 1336: $MD_SAFE_CAM_POS_PLUS (plus cam position for safe cam) and
- Modify MD 1337: $MD_SAFE_CAM_POS_MINUS (minus cam position for safe cam) and perform
POWER ON.
- Modify MD 1305: $MD_SAFE_MODULO_RANGE (actual value range for safe cam with rotary
axes).
Program Switch control OFF - ON.
Continuation:
301707 Axis %1 drive %2 parameterization of modulo value for safe cam (SN)
invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The cam modulo range parameterized for a rotary axis via MD 1305: $MD_SAFE_MODULO_RANGE
(actual value range for safe cam with rotary axes) violates the rule stating that only integral multiples
of 360 degrees may be set.
Reaction: Mode group not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. Change parameterization of the cam
modulo range in MD 1305: $MD_SAFE_MODULO_RANGE (actual value range for safe cam with
rotary axes).
Program Switch control OFF - ON.
