Members,
Is it possible to use TTL square wave rotary encoder with 500PPR instead of current interface 11uA with same PPR (both have A,A bar,B,B bar,C,C bar ) into TNC 407.

The 11µA uses a totally different interface so I cannot see it being possible.

Thanks AL_THE_MAN
I have another question

On a TNC 407, I have an spare encoder for X-axis siemens ac servo motor. It is not installed to the motor,

1. I want to connect it with the control unit.
2. By rotating it i want to see change in postition display of X just to confirm that it is in working position.

Is it possible

If it is the same type encoder you should be able to, the controller may give you a following error after so many counts.

it is possible only if you have the converter/adapter as well.

Dear kongzai,
Do you know some links from where to get adapter?

Dear kongzai,

i have no idea of what brand of encoder you are using.
just for your reference, i replaced a Heidenhain linear scale with a set of Fagor's + the adapter, for a much cheaper price.

adapter i used is for 1Vpp to 11uA conversion.
