#G540 fault light on for an instant serial#
I used the 8 wire motor in serial connection with the red/yellow and black/orange wires shorted and after cutting of these wires, the motor runs more smoothly and I got a light on the led at that coil that didn´t light before.

Do you think I can use that with the Gecko driver? And do you know where I can buy a new driver for best price? I have another new larger motor: 57BYGH78-401B 1.8 degr. I could light a led with one of the coils but not with the other, and I have tested the wires close to the motor, so I believe it must be a damage inside the motor. Motor label: KL23H251-24-8B When I tested the wires there was a difference between the coils. Solder can wick up inside the wire and when its flexed the wires break where the solder stops One possible problem you can have when you solder stranded wires to the bucket terminals on the 9 pin plug If you have used a single resistor to set the motor current its easier to insulate the terminals than trying to solder 2 resistors in parallel In addition you will need to check for short circuits between pins 7 & 8 (coil B- and A+)ĭid you fit heat shrink sleeving in the wires to insulate the terminals ? The volt drop across each coil and each pair of wires should be the same You can measure the voltage across the motor coils and then at the 9 way D-type plug Using a spare 9 way socket to make it easy to connect to the 9 pin plug on the cable If the power supply is set to provide a constant current of 2A the volt drop across the motor coil will be 2 x 3 = 6V Or set the power supply current limit to the current stated in the data and measure the voltage across the coilįor example if the motor data gave the coil resistance as 2 ohms the current as 3A and voltage as 6VĬonnecting a motor coil to 6V DC will result in a current of 6/2 = 3A What you can do is either apply the DC voltage as on the data sheet or label to one of the motor coils in turn and measure the current that flows Stepper motors will not run when connected to a DC supply ( the G540's case is just clipped together the motherboard with all of the external connectors is plugged onto the four G250 boards that are screwed to the lower half of the case )Īlternatively they will give you instructions for you to return the G540 for them to testĭo you have a bench power supply with a variable voltage output and current limiting ? That will enable you to use the G540 as a 3 axis driver while your waiting for the fourth G250
They will probably talk you through the disassembly of the G540 and removal of the four G250ĭrivers to find the faulty one that need repair / replacement If the RED LED is on with no motors connected
If you then get the green light, connect one motor at a time until you trigger fault so you know what is the problem I would disconnect all motors and check you can clear the fault ( just in-case its not the A axis that's the problem)
Its possible a faulty connection to the A Axis has damaged the A Axis driver and is triggering the E-stop / over current circuit

( the signal that turns the GREEN LED on also enables the stepper drivers ) When the RED LED is on all 4 G250 stepper drivers are disabled
