Note 1!
Active Cooling :
• The fan is activated at 60 °C and deactivated at 40 °C.
• The temperature limit of the heat sink for overtemperature protection is
dynamically set, depending on the overload limit.

• The duration of operation by maximum motor current is evaluated by a starting
temperature of 45 °C.
Note 2!
A line filter can supply several digital servo amplifiers, as long as I
