Tip!
It is reasonable to set a value ≥"4" in
0x10F1:2 to tolerate a failed PDO and prevent two PDO
failures in a row.
The following table lists some possible settings:
From version 01.02 , an extrapolator is available in the i700 servo inverter for the motor control
which can extrapolate the setpoints for one cycle. If two PDO frames fail in a row, no extrapolation
takes place anymore. The last value is frozen.
Monitoring to EtherCAT line interruption
This monitoring mode generally checks whether there is an EtherCAT line interruption.
• If this is the case, the i700 servo inverter changes to the "Safe-Operational" status and triggers
an error (CiA402 error code 0x8181).
• This monitoring mode cannot be configured and functions with and without "Distributed Clock
mode" (DC mode).

Setting for PDO frame failure detection
• If the internal frame failure error counter reaches the value set here, the Servo-Inverter i700 changes to the
"Safe-Operational" status and triggers an error (CiA402 error code 0x8700).
• From version 01.04 , the PDO frame failure detection is activated in the Lenze setting "20".
