"Cold start" parameter

"Cold start" parameter   

The "Cold start" parameter enables startup without connected motor or without main power.
If an ON command is received via the process image ("Motor direction of rotation 1" or 
"Motor direction of rotation 2"), the contactor is activated. If the "Cold start" parameter is set to 
"Enable", the contactor only remains activated if no current flow is measured.
If a current flow is detected during cold starting (no current flow on the activated contactor), a 
fault message appears and the device trips immediately.   

The table below shows the values for the "Cold start" parameter.
