Any one used the Motomatic II servo driver?
http://www.ab.com/motion/ec/Motomatc.pdf

I'm trying to set it up with limit switches as the wiring diagram shows in the manual, but it's not responding for the trigger of the switches to put the motor in revers. I hooked up every thing according to the manual.
Any one have any idea why?
Thx, Julius

At a quick glance it looks like you need to be able to use a external
velocity reference and a way to change the polarity of that signal to
reverse the motor.

I will look at it when I have a few minutes, 'Im sure someone has the
answer here on the tip of their tounge.

Motomatic does that. It has to be set CW/CCW mode and the limit switches should give the signals to revers.
I can revers or forward the motor manually, but it not respond to the limit switches.
I'm not sure if the INH or the COM has to be wired in to some how.

How?

From the manual:
>>Forward and Reverse Clamps (FAC, RAC)
The forward amplifier clamp (FAC) and reverse amplifier clamp (RAC) are directional clamps
which when activated stop the operation of the motor in the corresponding direction, allowing
operation in the opposite direction.
To activate or clamp the FAC or RAC, provide a logic "0" level. The input connection for the
FAC is P1 Pin 9, and the RAC is P1 Pin 10.
Figure 4.1 on page 4-1 illustrates the suggested method of connecting these inputs to the logic
level "0". P1 Pin 4 is common for the FAC, RAC and INH, application of this level will clamp
the amplifier.
Example:No Connection = Ok
Connection to Common = Clamped
Inhibit Clamp (INH)
This input signal inhibits or enables the output stage. This signal is also a logic level "0" for the
active status, and enters the drive through P1 Pin 8. P1 Pin 4 is the common for this input also.
This input is also used to reset the SSO fault circuit. The (INH) input must be put in the "0"
condition to clear the SSO fault. Switching from run to stop will also clear the fault circuit.
Example:No Connection = Ok
Connection to Common = Clamped
