FortiorTechServoStudio testing software
FortiorTechServoStudio
- FortiorTechServoStudio is a graphical user interface (GUI) that comes with the servo module to install, configure, and debug the drive. FortiorTechServoStudio can be used to debug drive parameters online and perform specific drive operations.
- FortiorTechServoStudio support two methods for initial system configuration：
- Using [General - Backup and Recovery], click "Default Parameters" to complete the initial parameter configuration, then configure the motor parameters in [Motor], and configure the encoder resolution in [Feedback].
- With [General - Backup and Recovery], the motor "Import Parameters" import previously configured motor parameter data.
FortiorTechServoStudio main interface consists of 5 functional areas:
- 1.Toolbar, containing common quick function buttons。
- Offline|Online – Toggle FortiorTechServoStudio online/offline and display the connection status. See section [Drive Online and Offline] 。
- Enable|Disable – Enable/disable the drive and display the enable status of the drive
- Save – Saves the parameters in the current drive RAM to the drive memory. It is recommended to use the Save button after configuring parameters to save parameter values in memory.
- No FLT — Clear drive faults. This bit turns red when the drive fails, and the motor can clear the fault.
- 2.information bar:
- Stop —Stop the motor and disable the drive.
- Help —FortiorTechServoStudio software online help. This feature is not enabled in this version of the software.
