Robot Controller
1

Dear All,

I’ve connecting 1 encoder to 2 outputs. 1 for robot and 1 for PLC. As long as I know, i think there’s no problem with it. But, can somebody share with me, is it secure or no ( to long periode usage)?

The things that I worry is about the current. With paralleling output, the current will be decrease. Or there’s something else that I must notice?

Thank you very much

Dear Majid

Yes, you’re alright, Encoder which connect to ABB must PNP and this Encoder type need 24VDC. Here are my experiences using Encoder on ABB Robot :

  1. Connecting 1 Encoder to 1 Robot and 1 PLC (NPN):
    No problem with some conditions :
  • I choose a low voltage Encoder (5 VDC)
  • I use converter (PNP to NPN and also 5VDC to 24VDC), It is caused my PLC need 24VDC and NPN
  1. Connecting 1 Encoder to 2 Robots :
    Until today I have no problem both using 5VDC Encoder-PNP and 24VDC-PNP for Conveyor Tracking purpose.

I hope It will help
