PCW, I am trying to use my 7i76 Mesa card’s spindle control to control the speed on my DanFoss Cyclotrol C150 controller. The manual says,
> "PROCESS CONTROL SIGNALS > A 0-10v dc control signal input may be used by connecting process signal(+) > to SP2 and process(-) to SP3. With tachometer feedback, the motor speed will > track the process voltage to better than 1 % linearity. The input impedance > is approx. 50K ohms. > Current process signals may be used with an additional resistor. A 1-5 mA > signal can be accommodated by shunting SP2 and SP3 with a 2.0K ohms, 1 /2 > watt resistor; for 4-20 mA, use a 500 ohms , 1 /2 watt. Set the "P" switch in > the closed (up) position, to allow the Cycletrol 150 to operate with current > process signals.” > OPEN SWITCHES (DOWN) > "A”, “B”, “C”, “D" > BASIC SPEED CONTROL > Control RUNS/STOPS from a single input command. > Closure on JOG puts Cycletrol into a RUN mode. > Opening the JOG produces a STOP command. I am not sure if SP1 should connect to Spindle+ or Spindle-. I am pretty sure SP2 should be SpindleOut. SP3 should connect to either Spindle- or Spindle+ which ever is left open after connecting SP1. Can anyone tell from the info I have furnished what the correct wiring should be. I am leaning towards Spindle- to SP3, SpindleOut to SP2 and Spindle+ to SP1. If I guess wrong will it damage the 7i76 board?
