CANOpen Echo

When I post a Motor Command via CANOpen, it is responding with the motor runtime command at 10hz. This is flooding the CANBUS with messages that I don't need. Is there a way to turn the echo off or reduce the frequency?

Hello,

This is part of the protocol we cannot do much about it. The solution is to send the motor command with one RPDO.

With current release RPDOs are hard-mapped to VAR values as shown in user manual, section "Receive Process Data Object (RPDO) Messages", p. 180. So you can write a script like the one in user manual, section "MiniCAN Usage Example", p.165.

Alternatively you can you Dynamic PDO mapping. This is not implemented in latest release, so we need to provide you with a beta eds and firmware. Then with the help of your CANOpen master you can map motor commands to one of the RPDOs.
