Sometimes during troubleshooting, a technician may request that you provide the firmware version currently installed on the inverter.
To find the firmware version, follow these steps:
- Press "Enter" button to access Main Menu
- Scroll down to "Advanced Info"
- Enter pass code "0-0-1-0" (press "Down-Down-Up"), then press "Enter"
- Scroll down and select "Version"
- Record the "Model" number and "Software Version" indicated on the screen. If "Software Version" does not appear on the screen initially, press the "Up" and "Down" buttons together for 3-4 seconds until the Software Version is displayed.
- The software version contains information on the firmware versions on the inverter. The first two digits represent the HMI firmware version, and the last two digits represent the DSP firmware version.
Six characters are displayed to indicate the current software version of the given unit.
XX YY ZZ
XX = HMI Version
ZZ = DSP Version
YY is for master/slave designation
In the shown example: HMI version is D2, DSP version is 01
