In addition to the classic output signalstorque transducers from HBM feature a Torque Measurement Communication (TMC) digital interface to improve flexibility. They can integrate with automation and control environments through both classic signals, such as frequency and voltage, and modern Ethernet-based field bus technology, such as EtherCAT. Integration is based on the modular and highly flexible TIM-EC interface concept.
TIM-EC is a two-channel EtherCAT interface module. RS-422 compatible rotational speed signals from series T40 torque transducers can connect to each other in addition to the TMC digital torque signal. The following measured values are available on the EtherCAT bus:
- Rotational speed
- Angle of rotation
The measured values specified above are transmitted in cyclic mode. Two low-pass filters (TP1, TP2) are available for the torque and rotational speed values; they can be set independently of one another.
