Overview of Alarms
SIMODRIVE alarms
300506 Axis %1 drive %2 NC sign-of-life failure
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: Upon servo enable, the NC must update the sign-of-life monitoring in each position control cycle. In
case of error, sign-of-life monitoring has not been updated.
Cause:
- a) NC no longer updates the sign-of-life as a reaction to an alarm (e.g. 611D alarm)
- b) Fault occurred during communication via the drive bus
- c) Hardware error on the drive module
- d) NC fault
- e) For 840D: Value of the machine data MD10082: $MN_CTRLOUT_LEAD_TIME (Offset of the
setpoint acceptance instant) is too great
- f) MD 1003 $MD_STS_CONFIG not set correctly (e.g. zero)
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not
ready).
Reaction: Mode group not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Channel not ready.
Remedy: Please inform the authorized personnel/service department.
- for a) Determine whether the sign-of-life monitoring failure is a sequential fault. A sequential fault
arises, e.g. through: Fault/alarm from axis x with an n-axis configuration. If this fault profile arises, the
above-stated error message will be isued for all n-axes, although there is only a fault/alarm at axis x.
==Remedy the error at axis x == sign of life of the other axes is irrelevant.
- for b) Check cable connection, perform remedial measures (check shielding or ground connection).
- for c) Change controller module.
- for d) See NC Diagnostics Guide and change NC hardware if necessary.
- for e) Correctly set the machine data 840D MD10082: $MN_CTRLOUT_LEAD_TIME (Offset of the
setpoint acceptance instant) with the machine data MD10083: $MN_CTRLOUT_LEAD_TIME_MAX
(Maximum settable offset of the setpoint acceptance instant).
- for f) Check MD 1003 $MD_STS_CONFIG.
Program Switch control OFF - ON.
