Looks like the compare A and the compare B need to be on opposite sides of the current count when set up e.g. M308>M301>M309

ACC-24E2A and UMAC Turbo PMAC2 CPU Trying to use the auto-increment feature on Channel 3 of the ACC-24E2A. It triggers once and increments for the next position (values in M308 and M309 change to the proper values) but doesn't seem to trigger at the next position. From reading the documentation it appears that once set up it should continue to output the EQU pulses at even intervals. I must be missing something. ; set up axis 3 (Y infeed) to generate EQU pulses M310=INT(M392) ; Set auto increment to integer portion of axis multiplier M308=M301+50 ; set position compare A (counts) equal to the current position +50 M309=M308+10 ; set position compare B (counts) for 10 (counts) M312=0 ; ENC3 compare initial state M311=1 ; Enable direct write (resets immediately to 0)

Thanks! That was what I was looking for.

No way to shut it off? How are you to send serial data to a display, for example? Looks like you have to write a program that manually stuffs a buffer and then writes it. Looks painful.

When I use SENDA"M105" in a program on a UMAC, it seems to always send STX and then the M105 characters. I can't locate anything about this in the docs. Would you please point me in the right direction? Thanks.

I purchased the PCommServer Pro2 Library and you sent me the documentation file since mine was corrupt on the CD. The file doesn't have many of the functions in it, for instance, GetVariableLong, SetVariableLong, etc. are these functions documented anywhere?

I have an existing UMAC system and I'd like to set up two temperature control loops. Nothing fancy, just control the setpoint and be able to know what the temperature is. I haven't chosen sensors yet, so I have a lot of options. On/off control is probably good enough. I know Ethernet to external controllers is an option but expensive. Any ideas?
