The actual lowest temperature is limited by the dew point. This depends on several factors, e.g. the ambient humidity and how quick the drive cools down after operation. Special care must be taken when the servo drive is actively cooled below ambient temperature.

Maximum values

The given maximum values can be achieved with a motor that is typical for robotic applications, reaching its maximum power at 60% of its RPM maximum. This case is used as a realistic assumption to specify the datasheet value for power. Beyond that, the servo drive itself is able to provide higher power, as it is able to drive its maximum voltage and its maximum current at the same time. In reality, no motor can consume both maximum values at the same time, so there is no operating point of the overall system (motor + drive) that would actually use the theoretical maximum power of the drive. As the calculation bases on a reference motor, there are setups with large motors that are able to even exceed the values shown here.

The maximum continuous output power and phase currents are highly dependent on the cooling situation. Please refer to our Thermal mounting considerations for details.

Load cycle

The maximum peak current is achievable for at least 10 seconds. The maximum allowable duty cycle depends on the cooling situation and load cycle profile. Under standard conditions (150 mm * 200 mm * 20 mm aluminium plate, 20° C ambient temperature, square wave load cycle alternating between 0 and max current), a duty cycle of 10% is achievable. The value can be higher for optimized system setups, e.g. 25% when using a SOMANET Node variant with directly soldered power wires or up to 100% if the mounting plate is actively cooled additionally.
