1.5 Operational safety
An extensive system of sensors and monitoring functions
ensures operational safety:
– i
2
t-monitoring
– Temperature monitoring (measuring the motor tempera-
ture and the power end stage temperature)
– Current monitoring
– Voltage monitoring
– Recognizing faults in the internal voltage supply.
– MTR-DCI-62...: Recognition of overvoltages in the in-
termediate circuit; brake chopper integrated.
– Drag error monitoring
– Software end position recognition
note the following:
• By the arrangement of the limit switches and, if necess-
ary, additionally by means of mechanical stops, make
sure that the axis always lies within the permitted posi-
tioning range.
• To detect a bus failure (wire break, master shutdown, ...)
activate Node Guarding as necessary on the CANopen
master; see section 6.5.1.
