I found a simple solution that works (for me):
I set the FSAFE_CTRL register that way, that if a failsave occurs, the master reboots. This way it resets the speed of all slaves, too.
I am currently playing around (communicating with a raspberry pi over I2C) with two of those drivers (one master and one slave connected over the expansion port). I am able to control motorspeed, etc. just fine. However I was a bit surprised, when I realized that the failsave only centers the master motorspeed (when I loose connection between raspberry pi and master). The slave drives on. He only stops when he looses connection to the master.
Is this wanted? What would be the best solution, if I wanted to disable all motors, when a failsave occured?
No public wish lists :(
