8.4.4 Telegram examples of the PROFIdrive parameter data channel (DP-V1)
In the following, a parameter read order and a parameter write order for a Servo Drive 9400
are described.
8.4.4.1 Example of read request: Query heatsink temperature
The heatsink temperature of the Servo Drive 9400 is to be read.
 Code to be read: C00061
 Heatsink temperature: 43 °C
