* These 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.

** The operating voltage is 12-48 V DC. The maximum supply voltage is only for buffering peaks when braking. The minimum voltage is for configuration purposes only. Please refer to our power supply instructions for details.

*** This is a fourth phase that can also be used for other purposes (see Manually controlling phase D voltage) it has a maximum current of 10 A.

[6]	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.
