Question:
What is the difference between process data channel and parameter channel in the device profile 'Lenze device control' when controlling the drive controller via Profibus?
Answer:
The device profile 'Lenze device control' is available both for the AIF module 2133 and for the Profibus FIF module. With the device profile 'Lenze device control' the drive is controlled by control word via the process data channel. This control word is partially transferred to code C0135 (control word of the controller). However, code C0135 can also be read and described via the Profibus parameter channel.
Important:
If the code is described via the Profibus parameter channel (e.g. bit 9 => 1 RSP), this cannot be reset via the process data control word. It must also be reset via the parameter channel.
Tip:
The drive controller should always be controlled via the process data control word.
