1.1.3 Operational reliability
A complex system of sensors and monitoring functions
ensures operational reliability:
ć Temperature monitoring: Final output stage in the
SFC−LACI and linear motor
ć Voltage monitoring: detection of faults in the logic power
supply and detection of undervoltage in the load voltage
supply
ć I 2 t monitoring / overload protection
ć Contouring error monitoring (e.g.Ăin the event of sluggishĆ
ness or overloading of the drive)
ć Software end position detection
ć Limit switch detection.
Note
Check within the framework of your EMERGENCY STOP
procedures to ascertain the measures that are necessary
for switching your machine/system into a safe state in the
event of an EMERGENCY STOP.
· If an EMERGENCY STOP circuit is necessary for your apĆ
plication, use additional, separate safety limit switches
(e.g.Ăas normally closed limit switches wired in series).
· Use hardware limit switches or, if required, mechanical
safety limit switches and fixed stops or shock absorbers
as appropriate in order to make sure that the axis always
lies within the permitted positioning range.
