To change the frequency from 50Hz to 60Hz on the VEVOR AT1-7500X inverter, adjust the frequency setting parameters. Specifically, set the desired frequency value (e.g., 60.00) in the relevant parameter controlling the output frequency. The exact parameter number is not specified in the context, but it typically involves the main frequency setting or run frequency parameter. Ensure the maximum frequency setting allows 60Hz operation.

You can't set the frequency to 60 Hz on the VEVOR AT1-7500X inverter because its maximum frequency setting is limited to 50 Hz, as indicated by parameters P15.17 and P15.18, which allow settings from 0 to 50 Hz.

To change the direction of the VEVOR AT1-7500X VFD to forward without changing wires, adjust the operation command settings. Specifically, set the run command to "Forward" using the operation panel or control inputs. Ensure the correct parameter (e.g., P01.02 Operation Command) is configured for the desired forward direction.
