Flashing

[hjl4]

Ok so I finally got my Viper 200's and they are mounted and wired according to the manual.
The board is powered by a 16VDC power supply.The Break out board, computer and Viper all share common ground. The high current side is isolated from this ground.
I have 96VDC going to the Viper servo motor control board.
Everything seems OK., until I turn the power on and try to program the Viper.
With the programming cable that I bought with the boards, 1 out of the 3 boards, refuses to let Hyperterminal communicate with it.
The two other boards are wired exactly the same, and respond to Hyperterminal very well.

But that is as far as I got.
There is a green LED on steady, and a rapidly flashing red LED beside it, that prevents me from programming or turning the motors on.
This is aggravated by the fact, that I can't do anything without resetting the board and 3 seconds, is not enough time to reconnect with hyperterminal, before the LED is flashing again. No time to change anything including the range settings. All I can do is read the encoder. The current warning for sure has not been exceeded, as the motors are not even connected and neither is the 96vdc input.
Reason why the motors are not connected? You can guess as to why, and I have been stuck on this all afternoon.

What does this mean.
Also, the Estop wire or pin, does it need to be connected? If so where exactly does it go on the Bob Campbell break out board?

And I thought rewiring the machine was tough. Relays are fun.

Any input will be greatly appreciated.

So are you saying that after 3 seconds you can't comunicate with the drive ??

Are these drive you bought recently, If so they have low voltage detection and the red LED will flash until you power the main side. But you still should be able to talk to the drive.

I don;t understand what you are trying to say. Call me tomorrow at the shop.
