I have a Pittman GM9413-4 Gearmotor that I would like to control. It has a max current draw of 1.44A. I originally wanted to have PWM control for the speed…but the motor runs very slowly (13 RPM with no load), so I don’t think this is necessary.
However, I do want a controller where I can specify the direction from a PLC. I also would like current sensing so I can tell if the motor is stalling or not.
I have been looking at the MC33887 Motor Driver Carrier and I believe it will work for me. I will be controlling it from a PLC. It looks like I will need a 5V and 12V line for the control logic and motor. I will also need PLC outputs for IN1 and IN2. How exactly is the direction chosen? If one is HIGH and the other is LOW it will go that direction?
Also, it says D1 and D2 can disable the motor driver. If I want to stop/start the motor from the PLC do I need to change both these pins? Or can I leave one HIGH and just change one of them.
It looks like I can leave the FS pin disconnected and EN needs 5V. The current feedback can go straight to my analog input at the PLC. Hopefully I am getting the wiring correct.
