Energy AX5xxx

The Energy AX5xxx module is suitable for energy monitoring of servo drives from the AX5xxx 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.
• Peak Torque: Peak value of the torque in Nm
  Process data: CoE: P-0-0094
• Interval (optional): By default, the input data is averaged over an interval of one second.

Input values

• DC Bus Voltage: DC bus voltage in 0.1 V.
  Process data: CoE: S-0-0016. Add that of the CoE S-0-0380 "DC bus voltage" to the PDO content.
• DC Bus Current: Input current to the DC link in mA.
  Process data: CoE: S-0-0016. Add that of CoE S-0-0381 "DC bus current" to the PDO content.
• Velocity Feedback Value: Motor velocity.
  Process data: CoE: S-0-0016. Add that of the CoE S-0-0040 "Velocity feedback 1 value" to the PDO content.
• Torque Feedback Value: Torque-forming current.
  Process data CoE: S-0-0016. Add that of CoE S-0-0084 "Torque/force feedback value" to the PDO content.
• Internal Braking Resistor Power: Braking power output via the internal braking resistor in W.
  Process data: CoE: S-0-0016. Add that of the CoE P-0-0209 "Internal braking resistor actual averaged power" to the PDO content.
• External Braking Resistor Power: Braking power output via the external braking resistor in W.
  Process data: CoE: S-0-0016. Add the CoE P-0-0210 "External braking resistor actual averaged power" to the PDO content.
