What I’d like to do is set a power of 10ish to my lift motors so they can hold their position without over heating during operator control with EasyC. How can I do this? Thanks for any help 
Are you currently overheating the motor? If you are giving it only a PWM value of 10, it should take a lot time for the motor to over heat.
My post was misleading. What I want is to set the power of 10. Because right now, for my lift to stay full height, I have to hold the button to raise the lift at full power causing overheating.
What I need is to know how to set the constant power of 10 during operator control.
Your problem requires a mechanical solution. You need another motor or the modify your gearing. Software can’t make your motor stop overheating.
