text: <s>[INST] Powerflex 753 will not run in reverse Hi Everyone We are trying to commissioning a Powerflex 753, the inverter is wired for reversible 2 wire control, with a a115v I/O module.When the forward input is on the drive starts and runs ok, the F appears on the HIM display, when the reverse input is on the drive starts in the same direction (forward) and the F flashes on the HIM ?The fwd and rev inputs are correct when I look at the Digin sts word on the HIM (Bit 0 fwd, Bit 1 Rev) which suggests the wiring is correct.the parameters 164 and 165 are set to look at the DI relevent bits, all the other DI parameters are disabled.Parameter 308 is set to unipolar (digital)As I said the drive will start and run OK, just in one direction !I suspect we have missed a parameter somewhere, but cannot see it even after searching the manualany help would be appreciatedThanksPeter [/INST] Two dummy questions at first: 1. Did you restart the drive after parameter settings ?2. The Fwd input is off when the Rev input is on ? (it MUST be ! ) Please, check also the following parameters and settings for 2 wire reversing control: - fuzzy logic \\n </s>
