Posted 12 Oct 2019 Hi Everyone! I need some help with configuring an inverter. The inverter type is powerflex 70. How can I set the next parameters. It should be work with two speeds. First: around 40 Hz. Second around 10 Hz. I think first I need to decide the direction, So I need two digital input for forward and reverse. Then I need plus more digital input, one for the high speed and one for the low speed. I guess I have connect dc 24 V too. I just dont know where should I connect this signal. I didnt find the properly manual. Do I forget something ? Can anybody help ? Thanks in adnvance! Share this post Link to post Share on other sites
Posted 14 Oct 2019 It looks like you want to operate at 2 preset frequencies, with reversing. Check out the installation instructions, page 32: https://literature.rockwellautomation.com/idc/groups/literature/documents/in/20a-in009_-en-p.pdf That page explains what each of the digital inputs does by default and lists the parameters you would use to change their default behavior. The user manual also has a lot of information: https://literature.rockwellautomation.com/idc/groups/literature/documents/um/20a-um001_-en-p.pdf Share this post Link to post Share on other sites
