300900 Stop A triggered
Scan
In monitoring cycle.
Effect
The drive is stopped with STOP A.
– Pulses are disabled via relay "Drive_IMP".
– Motor runs down
– Power on error
Explanation
There can be several reasons for triggering STOP A:
S
The time frame in MD 1356 of STOP B has expired.
S
The speed has fallen below the threshold in MD 1360 of STOP B.
S
The shut–down path test has been requested by the user by SGE "test stop selection", but the pulses were
not deleted after expiry of the time frame in MD 1357.
Remedy
The user must find the cause and initiate appropriate measures.
Note
Applies as from SW 5.4
300901 Stop B triggered
Scan
Cyclic in SI monitoring cycle.
Effect
The drive is stopped with STOP B. The pulses are then disabled via relay "Drive_IMP".
Explanation
There can be several reasons for triggering STOP B:
S
The safe standstill monitoring has responded.
S
STOP B was requested after STOP F, i.e. an error has occurred during cross–comparison.
Remedy
The user must find the cause and initiate appropriate measures.
Note
Applies as from SW 5.4
300906 Safe braking ramp exceeded
Scan
Cyclic in SI monitoring cycle.
Effect
The drive is stopped with STOP A. The pulses are then disabled via relay "Drive_IMP".
Explanation
Die Istgeschwindigkeit der Achse ist beim Bremsen mit "nsoll=0" (Stop B oder Stop C) nicht verringert worden,
sondern ist über die beim Bremsen nachgeführte Geschwindigkeitsgrenze und die in MMMMD_SB_STOP_N_TOL
(Toleranz Istgeschwindigkeit für SBR) eingetragene Toleranz angestiegen.
Remedy
Eingabewert des Maschinendatums MD_SB_STOP_N_TOL überprüfen.
Note
Applies as from SW 6
