Hey guys, I'm currently on a project using a US7-B5-TR22, one idea is to use the PWM output to command the frequency of an inverter. I know outputs needs to be enabled as a PWM output so I made a button to activate them when I use the inverter. The thing is that I don't have the inverter here to run some tests, and I wanted to see if the signals were as I wanted them to be. I measured them with an oscilloscope to verify and I can see that the output has the correct frequency, but the signals are about 2mV and of course really noisy. I'm wandering if I'm missing something here or if it's just normal ? In the documentation it doesn't say anything about it. Any idea ? Thanks you guys. Louis
Hello, I have the V700 with a Snap-In V200-18-E2B and a Inverter. I want to run a motor with a simple programs. I want the V700 communicate in RS485 with the inverter. I use a USB cable to send the program to the V700. I know i have to plug my RJ11 cables in the port of the V700 and set the communication on RS485 on the bottom of the V700. For the other part of the cable i have to take 2 of 4 wire and connect them on the Inverter. What i have to do after ? How i set the communication ? Will i have to create programs with contacts and coils to run the motor forward, or it have a compiled programs which contains some of these command ? Thanks,
Hi guys, I have a retrofit project for a small packaging machine using a M90-TA2-CAN. Among others, i want to control the speed of a 3-phase motor using a 0-10VDC analog output. The machine is already equipped with a Frequency inverter drive and the speed is adjusted by a 1K potentiometer. Now the customer prefers to adjust the speed via HMI... The drive has a +10V and ground source which passes though the pot and the wiper result is connected to speed reference terminal. There is no terminal for my 0V PLC analog output and therefore i can't use the analog output of my M90. Any ideas how to solve this problem? Thanks in advance, Kikis
