Motor speed does not increase to 127

Using the On-Line Window, when we run our motors they increase speed but stop increasing at around <-85 to 85>. When running the motors for our scissors lift arms, the motors stop running when less than -85 and greater than 85. Please help with any insight.

Thank you.

The Motor Controller 29 is at full throttle for Cortex motor speed values above about 85 and more negative than about -86. So the easyC On-Line Window motor response is normal. ROBOTC responds the same.

The determine why the motors stop running when your desired speed is above 85 or more negative than -85, use the easyC “Print To Screen” command. Set it to display what you are loading with SetMotor. If using ROBOTC, use the Program Debug window to step through the program and look at your variables.
