Operating The Drive - Siemens SINAMICS SM150 Operating Instructions Manual

Operation

8.2 Operating the drive

Danger when the permissible short-circuit currents are exceeded
Serious follow-on faults are possible, if the specified short-circuit current values are exceeded.
This can result in death, serious injury or material damage.
● Observe the maximum permitted short-circuit currents and maximum specified short-circuit
Subsequent damage after a full short-circuit trip of the circuit breaker
If, after a full short-circuit trip, the circuit breaker is closed again without first checking it, the
drive or the circuit breaker can be subsequently damaged.
● Before reclosing the circuit breaker, carry out a voltage check and measure the resistance.
Damage caused by incorrect parameter assignment
Malfunctions can occur if you change parameters.
● Do not change the parameters, e.g. for the motor circuit-breaker.
Note
To complement these operating instructions, the List Manual contains an overview of all
parameters as well as a selection of function diagrams to describe the operating principle.
