For MSD:
S
Pulse suppression, motor runs down
S
SIMODRIVE_READY and DRIVE_READY are cancelled

Pulse and controller disable corresponds to STOP A with SINUMERIK Safety Integrated.
For FDD:
S
Controllers are disabled. Motor is braked.

xx / xx With controller enable, the NC must
update the sign-of-life in each posi-
tion controller cycle. If an error oc-
curs, there has been no sign-of-life
for at least two consecutive position
controller cycles. Causes: NC fai-
lure, communication failure via the
drive bus. Hardware fault on the
drive module or HW error on NC
CPU if error occurs sporadically at
intervals of several hours. A further
reason: ring programming with GI or
gantry axes.

1.5.1 Alarm description
Remedy
During start-up with FFT or measu-
rement of the step response
– Switch off emergency retraction
– Switch off feedforward control
(MD 1004.0)
– Switch off min-max memory (MD
1650.0)
– Reduce number of DAC output
channels (max. 1 channel)
– Switch off variable signalling
function (MD1620.0)
– Switch off encoder phase error
compensation (MD1011.1)
– Select larger position controller
cycle for the NC.
– Increase the corresponding cycle
or the subordinate cycle (e.g.
current, speed or position control
cycle) or deselect functions which
are not required.
Check plug-on connections, take
measures to eliminate noise (scree-
ning, check ground connections).
Replace NC hardware, replace
servo control module.
