Gecko 320's startup for the newbie?

[DaSigntist]

Howdy I've got everything hook up and "FAULT" is all I get from the geckos.

I realize I will need to tune them after I get them going I just can't get them to get power to the motors.

My setup:
1100 oz/in servos with US Digital encoders 48 VDC

Power supply:
54 VDC 20 amp (two 54VDC 10 amp) I've got another to make 30 amp if needed.

Any thoughts to how to trouble shoot it?

I need a book "Geckos for Dummies" ;-)
I'm so lame on the electronics end of the scale.

I had the same prob at first with mine. But I reversed the power connections to the motor and that solved the problem. This may not be your problem though.

Thanks for the info...

The motors came pre-wired from Dean @ Axxus so for now I'll rule that out but will keep it in mind.

I'm using an Axxus breakout board as well if that helps as I followed Dean diagrams.

Jumper ERR/RES to ENC+ (terminal 5 to terminal 7).

Holy freaking support Batman!

Buy Geckos! Buy Geckos!

Thanks Mariss.
I got the fault light to go out after putting the jumper on and turned the limit and damp down as the motors were pulsating with the fault light going on and off but still no movement an any axis from MACH2 though.

Tun DAMP and GAIN to the 10 'clock position (8 'oclock = fully CCW, 4 'oclock = fully CW). Turn LIMIT fully CW.

The servo should "lock-up" then.

Reverse encoder channels A and B if the drive continues to pulse. Turn power OFF when re-wiring.

Oh ya!
It's ALIVE!!!!

Thank you again Mariss

Get Support = Buy Geckos

[Mariss Freimanis]

Thanks. Mind that you don't draw more than the motor's maximum rated continuous current. The motor should never get more than slightly warm.

Excellent, Thanks again.

Tun DAMP and GAIN to the 10 'clock position (8 'oclock = fully CCW, 4 'oclock = fully CW). Turn LIMIT fully CW.

That's exactly the same place I set them when I get g320's.

GECKO'S strikes again! They always come through when you need them.

I am having a similar problem, but this procedure is not fixing anything. I am setting up my G320 Drive for an Electrocraft 60v servo. I have been going through the testing procedure in the installation notes with no problems until I came to the point where you connect power to the servo. As soon as power is connected the servo will jump then wait about 3 seconds and then take off at I think its max speed. When any command is given the motor starts oscillating randomly and the drive faults. I am quite sure the encoder is good because when the motor is not connected, the drives faults every three seconds when a pulse source is given as stated. The gain and damping trimpots do seem to have random effects on this but I can't seem to find any position where the motor actually stays still. Anyone know what is wrong?
