Hello. I am controlling a Frequency convertor(Simovert Masterdrives Vector control) using 1215C Cpu and ET200SP. Analog inputs are connected to AI 8xI 2-/4-wire BA. I connected the wires according to the manual of the module, but the values tha I am reading is wierd. when the motor is not running it is roughly -4500 and when it's running -3800. channels are also set to 4-20mA. Attached there are the wiring and setting that I did. Thank you in advance. AttachmentAnalog_negative.zip (417 Downloads) |

Hello, yes, they are in twisted pair cable. updates about the procedure that I did. In the manual of the Siemens AG 6SE7087-6JD60 SIMOVERT MASTERDRIVES it's written it can be controlled either via 0-20mA or -+10V. For the analog output of my module (AQ 4xU/I ST ET200SP), I set it to 0-20mA but it didn't work at all, afterward, I changed it to 4-20mA and it worked which was pretty strange why it didn't work with 0-20mA. For the analog input (AI 8xI 2-/4-wire BA, ET200SP), I tried 2-wire and 4-wire connections but none of them gave me the right value. Attached you'll find the wiring and manual also. I really appreciate if someone can help me. AttachmentSimovert.zip (475 Downloads) |
