I am just going by the manual, not actually used one yet, but it looks like the FAC & RAC can inhibit each direction.
They can optionally be used for +/- limits sw.

so this dspMC?ip wil give 0 to 10 volt plus and 0 to 10 volt minus?
I tryed with a penlite battery both ways, but the drives don't reverse!???
thanks,
Cees
Look at post 7, it explains about the clamping. I suspect you have one of either RAC or FAC closed and the other open, that will only allow rotation in one direction.

I guess I will find out when I get it and play with it, I see there is a jumper that selects either RAM or EPROM for the PM module, so I guess if a RAM chip is fitted it is fully programmable, with the burn command?

All I can remember you being able to adjust and store were the normal tuning parameters, I certainly saw no way to be able to change the motor setup.

Yes I did see that, tried every combination,
they only rotate one way

This is maybe where the RS232 hookup would be usefull, in this case the Status report appears to cover quite a bit, including the FAC/RAC condition.

I am hoping to hook up a RS232 link this week end.
I was hoping that it would simply take the standard differential encoder feedback, but I suspect it needs that ABS signal to sync the commutation.
I would imagine it is just a single pulse, as after that the controller can use the encoder for F.B.
Unfortunately I do not have a motor to test.
I was hoping to use the amp as a spindle amplifier.
I will post the RS232 results when I get them.

This is what I found so far, I have to leave it for a while, but there should be enough if anyone wants to pursue it further.
The RS232 connection is:
P6 ---9pin Dsub
1 -----2
3------5
5------3

The original  Tandy100 was set up just as a dumb terminal mode.
I tried some of my Modem programs and found that Telix had the VT52 emulation.
I did not try all the others, I think if I spent time I may get one of the others to work.
I did get some spurious characters on the screen but it did not seem to affect anything, it takes a bit of practice to change the variables.
Only change jumper P10 when the power is off.
The protocol has to be set to 9600 N 8 1.
I tried ANSI.SYS in the Config.sys  file, but it did not make a difference.
I had nothing connected so when I switched on the amp, the Status screen stated that the thermal switch was open.
After jumpering it out, the two red status LED's went out.
The status screen only registers on power up.
You will probably need a Win98 or earlier PC and run at the DOS prompt.
I did not even try Hyperterminal, I have found it pretty useless anyway as a Modem program.

Hyperterminal works fine with these drives, I could easily see and alter all parameters that the manuals shows.
 What I couldn't do is write to the personality module to reconfigure the motor parameters, I hope you find a way to do that as I have 4 drives here that I may use in the future if I can get the motors updated.

The PM I have in the one I got is an SRAM IC, so the on screen variables can be changed with the S save.
Did you change the P10 jumper to enable write?
The manual mentions a Host mode and suggests obtaining the host mode communication protocol,  It is not clear what all  features are available in this mode, one is the save and load of the entire PM in Intel HEX.
I may try contacting Reliance if need be to get a copy.
