Error message: “Overtemp servo controller B154”

Possible cause:

This problem occurs, if the main switch of machine is turned on, but the machine is not running production for a longer period. The cooling plate of servo drive is heating up, because the water valve is turned off during this time, to prevent condensation water.

Turn off the main switch, if you don’t run the machine for a longer time.
To get rid off the error with overtemp. servo drives you can go to the „Tuning page“. Press the button to switch on the main valve for the cooling system manually. Keep this button pressed for a few minutes, the system will cool down and you can start the machine normally. If you close the “Tuning page”, the main valve is switching back to automatic mode, controlled by „Production ON/OFF“.
