Condition for status
transfer Description
10 Switched on"
−> Switch on disabled"
Fault reset = 0, Enable voltage = 0 or Fault reset = 0,
Quick stop = 0, Enable voltage = 1.
No serious error.
11 Operation enable"
−> Quick Stop active"
Fault reset = 0, Quick stop = 0, Enable voltage = 1.
No serious error.
12 Quick Stop active"
−> Switch on disabled"
Fault reset = 0, Enable voltage = 0, Disable voltage = 1.
No serious error.
13 From anywhere to
Fault reaction active"
Serious error, dependent on the device technology employed, which
forces normal operation to be aborted. The status transition is
independent of the control signals currently being sent.
14 Fault reaction active"
−> Fault"
The cause of the fault must be eliminated (e. g. overheating,
temperature reduced to permissible level). The emergency stop
reaction is completed.
A positive edge comes from the field bus on Fault Reset.
15 Fault"
−> Switch on disabled"
Fault Reset = positive edge and at least one of the signals Enable
Operation, Quick Stop, Enable Voltage and Switch on
not
1.
No serious error.
16 Quick Stop active"
−> Operation enable"
Fault reset = 0, Enable operation = 1, Quick stop = 1,
Enable voltage = 1, Switch on = 1.
Transfer defined via Quick Stop Option Code" 605Ah.
No serious error.
19 Fault"
−> Switched on"
Fault reset = positive edge, Enable operation = 1, Quick stop = 1,
Enable voltage = 1, Switch on = 1.
Note
This transition is not included in the DS402 profile. However, it is
required for drives with non−self−locking shut−off characteristics, so
as to avoid uncontrolled movement under load when the drive is
switched off.
