The encoder freq. in your datasheet max says 40KHz. Our controllers support an encoder up to a max of 30KHz.
Page 10 of the datasheet says the following.

Note1: Dual Channel controller max at 30Kcounts/s. Single channel version max at 1Mcounts/s.

Hi, Thank you. I also just figure it out after doing some measure with oscilloscope.
Maybe I need to buy a single channel model.
Thank you for your great support.

You should be able to convert via a firmware change for your controller.

You want the SDC21xxS firmware.

Sorry, You mean that I can use this SDC2130 with SDC21xxS firmware to make it a single channel controller? all I need to do is to download the new firmware to my SDC2130 controller?

Yes. The firmware will change it over. the only thing you'll do differently is to bridge the motor 1 and 2 channels to create 1 output.

M1+ and M1- will be bridged to create 1 lead, and M2+ and M2- will bridged to create the other output lead.

The controller should come back as SDC2130S in roborun+.

If you change your mind, you can always convert back to the dual channel by using the SDC21xx firmware.

Ok, its great. I didn't know that and couldn't find that info in the datasheet.
Thanks for support.

What about the wiring of the encoder passing from the dual channel to the single channel firmware?
..for the motors I have to bridge the M1+ with the M1- and the M2+ with the M2-
For me it is not clear where should I connect the encoder of the motor: pins 4-8 or pins 10-15?

many thanks

If the controller is single channel, then it means there is only 1 input, therefore a channel 2 no longer exists. Encoder 1A and Enc 1B are what you would wire up for.

You'll notice in the utility configurations after you change over to single channel that encoder 2 no longer exists.
