Hello

The Simoreg has been in store for several years. For a small project I decided to get it powered up again. Unfortunately the servo's do not respond to the input. On the control board a green and yellow led are burning. 

I found some documentation here on the forum to have it connected. In the documentation I found that the enable signal should be between the terminals 7(P24) and 64(RF). Without any result. Green and yellow led keep burning. 

I also noticed terminal 63 (IF). When I connect this terminal to 7 and 64, the relais engages closing 72 and 73.2 suggesting the Simoreg is ready to work. The green led is turned off and the yellow led remains burning.

I got a 3 volt battery with a variable resistance connected to the 14 and 56 terminal of the Z axis. When I turn the variable resistance I can hear the transformer noise is changing a little bit. But the servo is not moving. 

Voltages on the several terminals seem to be ok. The 3 phase 400 AC and 200 DC are available. Also the fuses are ok. I can not find the meaning of the led's and I do not see any other ways to debug why the Simoreg is not working. Your support is much appreciated! 

Regards Rene.

Hello,

Please refer Simoreg 6RB-2025 post, wherein refer reply byO_Moderator. Simoreg 6RB manual is attached which may help you. 

I found this manual. But it contains no information for trouble shooting or led information.

Regards.
