G214 MANUAL STEP MOTOR DRIVE Thank you for purchasing Geckodrives G214 motor control. The G214 is a from-the-ground-up stepper motor controller design and uses multiple proprietary techniques to run a stepper motor smoother, quieter and with more power than other drives in its price range. This document seeks to quickly get your G214 up and running and will explain each new feature and its utility for your application. Lets begin: KEY NEW FEATURES OF THE G214: 1.) Form, fit, and function compatibility with IM483 and IM805 applications. The G214 was designed as a drop-in replacement for the discontinued IM483 and IM805 stepper motor controls. Dimensions and pinout are identical, but with the numerous technological advantages of a modern stepper drive. 2.) Next-generation resonance compensation. Midband instability and resonance is compensated for using all new algorithms, eliminating resonant frequencies at the midband completely. 3.) Extra resolution choices. Ranging from half-step to 256-microstep resolution, a stepper motor can be run with resolution of up to 51,200 pulses per revolution. Backwards compatibility with decimal resolution motor controls, such as our G203V and G201X, allow for minimal parameter changes in software and programs. Binary Decimal Resolutions Resolutions 2 5 4 10 8 25 16 50 32 125 64 250 128 256 4.) Push Button Self-Test. Testing and tuning stepper motors can now be done simply with an onboard self-test button. Simply pushing and holding this button down will run the motor CW and CCW at low speed, allowing easy tuning for motor resonance with the onboard adjustment trimpot. 5.) Resolution upscaling at low speeds. Every microstep is further broken down into higher interpolated microsteps to increase motor smoothness at extremely low speeds. The resolution upscaling will change depending on the microstep resolution chosen via DIP switch to be sure your motor is getting the smoothest possible operation at all times. 6.) User adjustable standby current. If the onboard DIP switch is used to set phase current the user can adjust a trimpot for holding torque from 0% - 100% current in standby mode. If an external resistor or voltage is used the user may use a second resistor to set standby current, allowing full customization on multi-axis applications.
