Simple Speed Control

 

PURPOSE: Driving a motor using the onboard trimpots as a speed controller.

PRODUCTS TESTED: GM215

SETUP: IN2, TRIM4 and TRIM5

Many simple motion applications require a set speed on a motor when you turn it on. This will allow you to set the speed once manually and be able to turn the motor on indefinitely at the push of a button. 

Initial setup for this requires a momentary switch going from IN2 to +5V, with the negative of your 5V supply going to COMMON. Be sure that your GM215 is set to EDIT mode and is assigned the proper axis designation according to the DIP switches.
