Notes
- Gen4.2 firmware update MUST use the compatible I-con Desktop v2.99.0.0. or App v2.2. Previous I-con version such as v2.96.x could cause irreparable harm to the motor system.
- Only limited compatibility. Contact Infinitum prior to design, installation or usage.
- I-con 2.99.0.0 will support Gen4.1 firmware (CIM 4.8.0 and INV 4.7.0). However, Gen4.1 will not support the new CIM and INV features, Save State, HEX Diagnostics or the Statistics Files.
- App version 2.2 is only compatible with Apple IOS.
- App v1.2 is generally compatible with Gen4.2 but firmware update functionality is disabled.

Update Recommendation and Availability Date
We recommend Gen4 units currently in the field be upgraded to the latest version to benefit from the above features and enhancements.
| Product Category | Firmware Availability |
| Units to be shipped from Infinitum factory | The targeted ship date for units carrying Gen4.2 CIM and INV firmware is November 2025.1 |
| Units currently installed in the field and running Gen4.1 version of firmware (Gen4 installed base) | Contact support@goinfinitum.com for the Gen4.2 package (CIM, INV firmware, I-con software) to discuss compatibility, update process and special instructions. |
| Units currently located in a warehouse carrying Gen4.1 firmware | |
| Units currently installed in the field and running Gen2 version of firmware (Gen2 installed base) | Gen4.2 not applicable. |
[1] Note: Customers who must retain an existing firmware revision, including those with PPAP requirements, must submit a written request prior to shipment.
Frequently Asked Questions
| Q1. How can I check the firmware version currently loaded on a motor? | A1. Use the I-con desktop or mobile app. Contact support@goinfinitum.com with the Serial number or nameplate image if I-con connectivity is not feasible. | |||
| Q2. Is I-con 2.99.0 backward compatible? |
A2. Yes. I-con 2.99.0 is generally backward-compatible with previous versions of firmware and hardware except for Gen4 motors manufactured prior to October 2024. Gen4 motors manufactured before this date use an incompatible boot loader and therefore are not suitable for Gen4.2 upgrade using Icon 2.99. Icon v2.99 automatically parses the serial number and active CIM firmware version to determine compatibility. If incompatible, an error message will appear (see below). Please contact Infinitum support and refer to PN# 25-05 Gen4.2, Special Upgrade Instructions for additional information. |
|||
| Q3. How can I find more in-depth information or training about the new features in Gen4.2? | A3. Contact support@goinfinitum.com | |||
| Q4. The motor is working fine in the field. Is an update to the motor to Gen4.2 mandatory? | A4. Updating to Gen4.2 to benefit from the improvements in this release is recommended; however, the decision should be based on engineering judgment and an analysis of your specific installation. Please consult with Infinitum Support or the Application Engineering team prior to updating any production system. | |||
| Q5. How can I access the release notes? | A5. Contact support@goinfinitum.com for firmware and software release notes. | |||
| Q6. How does this release impact MST? | A6. All of the above changes are reflected in the latest version of the MST. | |||
| Q7. How can I distinguish a Gen2/3 hardware from a Gen4 hardware in the field? | Gen2/3 hardware has a circular shaped drive and catalog numbers on the nameplate start with the designator ‘IES’. On the other hand, Gen4 hardware has a square shaped drive and Catalog numbers on the nameplate start with the designator ‘AE or AH. More info on Gen2/3 is available on the Infinitum support site under the legacy section. | |||
