Hi, I have a LOGO 8 with the analog extension. I'm controlling two motor controllers (MC) with 0-10V. AQ2 connected to MC1 is working properly, outputting 0-10V on command. But AQ1 connected to MC2 is not working as it should. It only gives me portion of the Voltage I write to the analog output. I have tried to swap the MC's and AQ2 works with both MC's as it should. What happens is that when I output 5V it only gives me 3.2V, and when I output 10V it only gives me around ~7V. When the output is not connected to the MC and I measure the output with a multimeter (10Mohm), it reads correct values. I have measured the amper usage under 10V output and it stands around 110 micro ampers when it should be taking around 154 micro ampers The MC input resistance is about 65kohm. Included in this post is the project and the schematic of the device I built containig the PLC. AttachmentProjectMC.zip (177 Downloads) |

Have you tried just one controller to connect to AQ1, the second controller to AQ2 at the same time not? |
