DirectMode: Direct operation
By using the MDP92A power supply module with controlled DC link voltage, the DC link can be set to a higher voltage than is possible with the normal MDP90A supply module.
Through this increase, the performance in the axes can be increased even without using a storage unit.
The connected load cannot be reduced in this operating mode. All monitoring functions are available in combination with a controller from SEW-EURODRIVE, which allows for energy monitoring.
The advantages of DirectMode are:
- The power supply module can be operated within an input voltage range of 3 × AC 200 V to 500 V. The DC link voltage can be set independently of the input voltage.
- This enables short-term operation of drives with higher speeds.
- For application testing, the device is suitable for precise data collection. Regarding energy and power, the application can be measured in various operating modes. With the data collected by the MDP92A power supply module, the application can be examined for optimum use of a storage unit that is potentially required.
The following figure shows the functional principle of the components of the Power and Energy Solutions in DirectMode:
