Properties of the service and operation mode switch 
SIMOTION D4x5 has a Service selector switch and an operating mode selector switch in the 
lower section of the front panel. 
The switch on the right labeled PLC is used for switching the operating mode of the 
SIMOTION D4x5.  
The Service selector switch on the left (labeled SIM/NCK) is for service and diagnosis 
functions only. In "normal" operation this switch must remain in the 0 position (see figure 
below).
