Hello, I am using a couple of DMC60C with an NI-XNET USB 8502. I have had some good luck but am running into a very specific question. The control message: 0x02060000 Uses a signed 24-bit integer for both closed loop velocity and closed loop position control setpoints. However, the makeup of that value is only loosely described in the documentation. My questions are: 1) is the byte order as shown in the manual correct? It appears strange to go trgtH in byte 3, targtL in bye 4, and trgtM in byte 5. I could understand H, M, L or L, M, H but it seems oddly shuffled as presented. 2) is a negative 24 bit value stored as 2's complement? Thank you for any advice. My motor does not appear to like the values I have been sending for velocity control mode. Sincerely, Brian
I am looking at the DMC60c CAN protocol guide and also the software API reference manual. What are the API numbers needed in the CAN message to communicate with the DMC60c. For example if I wanted to send a voltage command using the function driveVoltage, what should go in the API field (Byte 1) of the message identifier? Thanks, matt
Close full duty cycle (93% in attached images) the DMC60 pulses through zero to -12V and upon trying to recover causes an over voltage failure on the power supply. This happens unloaded and with a small load of 4Amps. Anyone else have this issue? Cheers, matt The onset of this behavior can be seen as you increase the duty cycle you get an occasional incorrect extra pulse as shown in the following figure
