Your electrician is welcome to call 3Dtek with any questions.The VFD Wiring Diagram above is for your electrician! 240V wiring and VFD’s are so very dangerous, please don’t risk doing this yourself.The invertek E3 VFD has several important and several optional parameters to be set before attempting to operate.
#G540 programmer manual manual#
see the gecko manual linked above for information on its use. Lastly, an opening in the board to access the smoothness adjust trimpot, which can largely be ignored.
If your motors are running overly hot then turn this down a little, if you are suffering from lack of power turn this up a little. The desired resistance measurement between the two terminals is 2.5 to 3kOhm.
There is also measurement point beside each trim pot marked in blue. Note that this is not smoothness tuning the trim pot mentioned in the manual. This takes place of the resistor to be soldered that is mentioned in the G540 manual. The GRBL Gecko controller has a trim pot for setting the current limiting of each stepper motor which are circled red in the image below. Please ensure the charge pump switch on the gecko is turned off. Our implementation of this device overrides some of the information provided in the manual, for example, the motor current tuning and motor wiring. Gecko Drive G540 and GRBL Gecko Controller Settings.įor reference, the G540 User manual. The cooler will be marked for either 12V or 12-48V connection. 
The Control Card is pressed onto the top of the G540 and holds its self in place firmly.The Cooler plate sits below the G540 on its shorter standoffs, with the fan’s sticker side facing the bottom of the G540.
The Gecko G540 and Cooler are mounted and separated using standoffs. PLEASE READ IMPORTANT NOTES AT BOTTOM BEFORE POWERING UP THE VFD!!!!
