Partial 320?

[John3]

Hi,

I have used 320 servo amps in the past with excellent success, truly a great product! I have a retrofit project now where they just won't have enough power.

The present machine has an old beat controller but excellent high power servos that have no problems. These servo motor/amp packages have tach feed back and accept +/- 5 analog control. They control 190 VDC @ 30 amps.

My question is, can I use part of the 320 circuit to perform the step-pulse to analog conversion and encoder interface? I'm thinking I could just tap off the error voltage point of the 320's and drive my servos.

Or does a product like this exist? I think there should be a 3xx version available for this purpose. I see several applications at our shop for this sort of thing.

Check with PMDX. I believe they have a Step/Direction to +/-10V converter.

Here is a step/direction driver

The Pixie P100 is a step/dir to +/-10V or +/-5V analog server controller board. It does however require encoder feedback and will not work with just tach feedback.
