It has come to my attention that 2 users of the G210 and G340 drives
have experienced missed steps. I have just now been able to replicate
this problem and will be working on a solution for it.
The problem occurs when BOTH of the following conditions occur:
(1) Multiplier set to X1 or X2 (5 uSteps and 10 uSteps)
(2) Very rapid or no acceleration from 0 speed.
There is no problem when the multiplier is set to X5 or X10.
For now I recommend using only the X5 or X10 settings. I will send at
no charge HCPL-2531 opto-isolators to those that must have X1
operation. Remove the G901 board and replace it with the opto to get
X1 operation.
I should have a clearer idea of a cure in a few days. I apologize for
any problems this may have caused and will do what is necessary to
correct it.
