This problem I have has been going on for some time and I am at the point of throwing everything out and starting fresh with products (industrial, generally not for sale here). Everyone seems to say it is something else is causing the problem.
I am posting here as the unit showing a fault is the Gecko drive.
First, everyone I contacted has provided help.
I have a CNC lathe running under Turbo cnc. After about 30 minutes, one drive loses holding torque. If I reset the Gecko drive (one of the pins), the holding torque comes back. If I turn the power off to the drive/motor, I can use the system again after about 20 to 30 minutes. Will go through the same problem.
I have both drives running under G212. I have used 3 different drives on the axis and the same problem occurs.
I have a Keling NEMA34 SINGLE SHAFT STEPPER MOTOR 400 oz-in and an 1160 oz one on the problem axis. 4.2A/ phase.
Power supply is a 65 VDC 6ADC from Transformer Technology. I contacted them and the power supply should be good.
I have also changed the computer in use.
I contacted Gecko drive and the problem was the unit shutting down due to an overload. Suggested I change the motor.
I installed a 400 oz motor on the problem drive ( dual shaft as out of stock on single shaft).
The lathe worked like a dream!
For hours on end with no interruption or lose of holding torque.
Until this afternoon.
The same problem returned
I shut the system down to cool. No effect.
For the record, I was advised I needed a breakout board. I ordered one from Campbell Designs and was trying to install it but ran into problems. ( seems not easy for Turbocnc use). I did email back and forth with Bob Campbell but had to put this on hold until I had more time.
