Setting The Monitoring Of The Communication - Siemens SINAMICS G110M Function Manual

Communication over CANopen
6.7 Integrating the inverter into CANopen
Activating node ID or baud rate
Procedure
To activate the changed node ID or baud rate, proceed as follows:
1. Switch off the inverter power supply.
2. Wait until all LEDs on the inverter are dark.
3. Switch on the inverter power supply again.
Your settings become effective after switching on.
You have now activated the changed settings.

Setting the monitoring of the communication

To monitor the communication, use one of the following methods:
• Node guarding / life guarding
• Heartbeat
Node guarding / life guarding
Principle of operation
● Node guarding:
Is always active if heartbeat is not activated (p8606 = 0). Node guarding means the
master sends monitoring queries to the inverter which then answers.
The inverter does not monitor the communication. Set the responses to a bus failure in
the master.
● Life guarding:
is active if you use p8604.0 and p8604.1 to set a lifetime ≠ 0.
Life Guarding means that the inverter monitors the master's monitoring query and reports
fault F8700 (A) with fault value 2, if a life guarding protocol (life guarding event) is not
received within the lifetime. Set additional responses to a bus failure in the master.
Calculate value for lifetime
Life time = guard time in milliseconds (p8604.0) * life time factor (p8604.1)
