Hi, You need to make sure that they are using brand new (October 2013 or later is when the Toshiba engineer told me the new design would be ready) TB6600 chips. I found an error with the timing on the older version chips (pwm at zero crossing). They had to recall all of the chips. I ended up sending several thousand chips back. Fortunately I found the problem right before I was ready to ship any product. It is an very intermittent problem and only shows up in very limited circumstances. You might be able to use it for something like a pump, but don't use it for motion control where position is crucial.
