Hi,
This is my first post I am a mechanical engineer with small electronic knowledge.
I am looking for some help in constructing a circuit .
I have a small cnc lathe and I would like to program multiple speed changes within the program. The motor is a 90v dc motor.The control circuit has a manual 50k pot giving 0-7.8v nominally to control the speed.
I can program an m26 command which will give me an output of logic pulses with a frequency of 100hz, the number of pulses being programable up to 221, initial condition-lo
The main program is interrupted during the output time and then subsequently continued.
I need a circuit that will let me input a number of pulses using m26 to create a voltage I can insert into the motor control circuit .Then hold that voltage until a new string of pulses is input changing it to a lower or higher voltage and so on.
John
