SBL1360 goes into STALL detection after firmware update

4 years 8 months ago #29531548 by Herman
I replaced a SBL1360 controller (had strange behaviour, will contact support) to a new one and updated the firmware to v1.5.

After the update the controller goes into stall condition.

I re-installed the old firmware (v1.4b) and the controller runs ok.

I use the controller in closed-loop speed mode with a quadrature encoder.

Can you help me?

Hello,

we can assume that the encoder stall detection is causing that, since it is a new feature. We are not aware of your setup in order to tell for sure. If you disable the stall detection it will be ok.

I have the stall detection disabled but the fault exists (Status flag FS=17, Stall detection BLSTD=0)

You asked for the configuration:

Encoder: industrial optical encoder AVAGO HEDS-9040#B00
Firmware ID: Roboteq v1.5 SBL1XXX 10/01/2015
Operating mode: Closed Loop Speed


I did some debugging with Roborun+ (latest version)

- if I enable stall detection (+save2C) and then disable stall detection (+save2C) the controller will run, but if I recycle the power the controller goes into stall condition again (read stall detection BLSTD=0)

Hello Herman,

This seems to be a firmware issue. In order to have more clues:
  • Please check if the problem is there with open loop.
  • Save your configuration profile and post it here or send it in This email address is being protected from spambots. You need JavaScript enabled to view it..

In open loop there is no fault.

I will send the configuration files to techsupport

Was anything found out about this issue? I seem to be seeing the exact same issue on an HDC2450 running brushed motors in closed loop?
