The amplifier shows warning n17 after replacement of a S300 or S700. The old drive did not show any problem with CAN or EtherCAT. How can I reset the synchronized fieldbus operation?

Set BUSP1 to 1 and finalize the configuration change with SAVE and COLDSTART.

Background: Bit 30 (COB-ID Setting for Tx-PDO) is supervised since Firmware 2.51. The amplifier sets the bit and expects the COB identifier is written with set bit 30, too (means: no RTR request of TX-PDOs is possible). 

If bit 0 is set to 1, then bit 30 is not supervised any more.
