12Lf Force control lineup

mightyZAP FORCE Control 12Lf Series 27mm stroke firmware update (Oct, 6th, 2021) (Minor update on Feb, 28, 2022)

2021-10-06 19:24

We are happy to release the updated Firmware for all mightyZAP actuators. (V21 for Position control lineup  and V2.1 for Force control lineup actuator)
On this page, you can update the firmware for the FORCE control 12Lf series 27mm stroke actuator. Please check the firmware version of your actuator on the Manager software, if it is V2.1 or lower, please update the firmware for performance improvement and some bug fix.

If your actuators already have V2.1 indication along with the production lot number on the model plate sticker, you do not need update.

  • IR-USB01(or IR-USB02) PC USB interface is required to update the firmware on the Manager software.
  • Please install the new Manager software V3.1.1 optimized for the new firmware. [Download new manager software & update manual]
  • Make sure to install the correct firmware that matches the model name of the actuator you have. When you download the update file, please pay attention to the model name.


    • If the old firmware has been already applied to your existing equipment, be sure to test the new firmware with the equipment for verification. Although the actuator specifications are not to be changed through firmware update, the operating characteristics may be affected  depending on the characteristics of the equipment, so please be sure to test  the actuator with the new firmware in the equipment.
    • Make sure to download correct model named firmware for your mightyZAP. Download the concerned firmware correctly according to your actuator model.
    • Update single servo only. Do not update with multiple qty of servo motor under serial connection(daisy chain) at the same time.  Otherwise, it may occur some error.
    • In case that incorrect firmware is installed, please process the update with correct firmware update file again.
    • Before update, make sure if all wirings (communication wire, power wire) are properly connected between IR-USB01(or USB02) & actuator / between PC and IR-USB01(or USB02).  Then, please do not touch them while updating  as it may occur fatal communication error.  Please contact factory if communication or update error continues.
    • Stroke calibration process will be automatically made after firmware update. So, before firmware update, make sure if actuator is standalone(should not be connected with any mechanical stuff of your application) for proper calibration.

    [V21 - What is updated?]

    • Save failure issue is resolved after reset for Min/Max Position Calibration (Saved Min/Max Position Calibration data can be saved even after Reset)
    • Save failure after Current Limit setting has been fixed.
