Encoders for Gecko drive

[quickerz]

Hi all.

I have a question regarding encoders for Gecko 320 servodrives. Will encoders as seen in attatched datasheet work with the 320 servodrive?

that doesn't look like it would be easy to mount or hook up.. i cant say if it would work thou

these are recommended as you can change the resolution. i got the us digital ones and wished i would have gotten these

Ok.

They are already mounted on a type of motor. it says that they are ttl compatible. Maybe I should contact Gecko to be sure.

how many line are they? with the non selectable error range on the older geckos much more than 500 line the drive errors out in a really short distance. if you have the new drive this shouldn't be a problem.

looking at the specs it seems to be under the current rating and of the correct type.

The pdf you supplied says the device needs 65mA at 5VDC. That knocks it out of the water right there because the limit on what the G320 can supply is 50mA.

cant you just power them separately and use a resistor in the gecko?

Precautions for Use
( 1) This module is designed to be operated at I F = 30mA TYP.
(2) Fixing torque : MAX. 0.6N • m
( 3) In order to stabilize power supply line, connect a by-pass capacitor of more than 0.01µF between Vcc and GND near the device.
( 4) As for other general cautions, refer to the chapter “ Precautions for Use . ”

Actually that is an absolute maximum rating. The device requires external resistors to reduce the current for the internal led (1 Anode/2 Cathode) to 20mA. The maximum it should operate at with both output A and B at low (Sinking current) should be 30mA.

I'm try to use those CUI AMT102-v with a G320x but I can't get them to work. I'm not sure where the problem is; I mis-wired it first but got that fixed. The voltage on the A & B lines go from 4.9v down to .5 but when I spin the motor the drive faults out...

I just completed hookup/tuning of the AMT-102 with the G320X and it works well. Will use this encoder for future needs. Did call Marisis couple of times just to clarify and guidance as this was my first wiring of a drive. With his help it when smoothly following installation instructions.

Did you glue the plastic adapter to the shaft? I think that my problem is caused by slippage...
