Compact little critters Gregg, no spare shaft to grab with a roller
sprag. Besides, I tend to think in electronics terms
Find or make a one way ratchet or roller sprag to fit to the pump motors so
they can't spring back.

How do I turn this motor by hand? its
If the motor is expensive or hard to get, keep it and use a driver rated
for more volts.As said, you can buy four MOSFETS and make a driver that
is good enough for a use-case where A/C mains is available and you are not
trying to squeeze every drop of power from a battery. Homemade h-bridges
You can set the VNH3SP0 to "brake" mode. But this works or not depending
on the motor and gearing. It is very easy to test if it will work. Twist
the leads of the DC motor together. With shorted leads, the DC motor
should resist rotation, to what degree depends on the motor. The other
mode

The 7i77 is +/- 10V so you would want to use an "abs" module to make
sure that the 7i77 analogout doesn't see the negative spindle speed
commands
Then
hey everyone
I have a fanuc velocity amp which I have hacked and found the 0-10v speed
reference input on it. the amp takes in 0-10v and Rev/FWD inputs. this is
ideal to control with a Pot and two switches and how I am currently
controlling it. On my cnc mill i used a 7i76 card and the virtual
Hello!
I am looking for sample config for machine with 7i96 board. Only thing
I have found so far is JT's config utility, but I feel more
comfortable taking a sample config and editing INI and HAL files. Is
there anything like that available?
