SBL1360 Questions CAN and Encoder Questions

Hello,

I'll soon be starting a project where we are looking to use many SBL1360 controllers operating in many modes on a single robot. I had a few questions to confirm information in the SBL1360 datasheet and user manual.

1. Does the SBL1360 support the RoboCAN protocol? The datasheet indicates, CANOpen and the proprietary MiniCAN and RawCAN. I was hoping the features of SBL1360 might have been updated to support the meshed network.

2. If the SBL1360 doesn't support RoboCAN, what is the best way to get up to speed on implementing some sort of motor control protocol over CAN using MicroBasic scripts? Are there videos or additional documentation that covers the basics?

3. When operating in a "Closed Loop Position Tracking" mode, does the SBL1360 support an absolute magnetic encoder which outputs a PWM signal where the duty cycle is proportional to the position of the encoder. Specifically, I'm interested in the following type of encoder operation in PWM mode:

What configuration parameters should I be looking to set to support such an absolute position encoder as input to the close loop PID? You can point me to specific manual pages/sections to read.

That should do it for now.

Thanks,

Mike

Blake,

Thank you for the quick and detailed answers. It's good to know that RoboCAN is an option on the SBL1360.

Also, we are looking at the FBL2360 because it may be easier to mount in our application given it's in a plastic and metal container. So let me ask you the same question about the FBL2360.

Does the FBL2360 have different absolute encoder options? For instance, does the FBL2360 support absolute encoders with a PWM output as linked below? What about the same encoder, but the analog version where the absolute position is output as a voltage between 0v and 5v?

Or, is it limited to just a SSI or SinCos sensors for absolute positioning?

Thanks,

Mike

Hi Blake,

Concerning the SBL1360, although it doesn't support absolute position encoders, the datasheet indicates the following: "Closed loop position control with encoder, analog or pulse/frequency feedback". This indicates we can implement absolute position control if we use an analog signal (ie. potentiometer voltage divider) to indicate absolute position. Correct?

Unfortunately, the datasheet is a bit ambiguous as to how position control is implemented on the SB1360. It would be best if it described the specific modes from the user guide that are implemented in the SBL1360.

Thanks for your help.

Mike
