Energy AX81xx

The Energy AX81xx module is suitable for energy monitoring of servo drives from the AX81xx series. The input data is averaged over a configurable interval and then calculated. To ensure that the required input data is available, it must be added to the process image.

Optionally, a Boolean signal can be selected for the Enable Execution input so that the algorithm is only active if the value of the selected signal is TRUE.

Configuration options

• Sample Rate: Sample rate of the system to be analyzed in Hz.
• Interval (optional): By default, the input data is averaged over an interval of one second.

Input values

• Electrical power: Electrical power in W.
  Process data: Enable PDO input 0x1A32 and add CoE 0x3242:12 "Electrical power" to the PDO content.
• Mechanical Power: Mechanical power in W.
  Process data: Enable PDO input 0x1A32 and add CoE 0x3242:13 " Mechanical power" to the PDO content.
• DC link voltage: DC link voltage in mV.
  Process data: Enable PDO input 0x1A00 and add CoE 0x6079 "DC link circuit voltage" to the PDO content.
• Motor Brake Current: Brake current of the motor in A.
  Process data: Enable PDO input 0x1A20 and add CoE 0x3001:01 "Actual motor brake current" to the PDO content.

Output values

• Electrical Power [W]: Electrical power in W.
• Mechanical Power [W]: Mechanical power in W.
• Braking Power [W]: Braking power in W.
• Electrical Energy [Wh]: Electrical energy in Wh.
