In Imotion MCEWizard ,How does imotion achieve constant torque?
As far as I know, it can be set in "CurrentControl" first, but how to write the script program afterwards? How to set up PI? If you use VSP or DUTY to control, how to write SCRIPT?

Hello,
You are correct. To achieve constant torque, disable the speed loop control and select current control via MCEWizard or in MCEDesigner/Script by setting ctrlModeSelect to 1. When current control mode is selected, IqRef_Ext and IdRef_Ext become available. IqRef_Ext has a direct influence on torque. Additionally, you can set KpIreg in Script or MCEDesigner. See our Software Reference Manual, section 4.2 for notes on Current regulator tuning

Thank you for your reply!
Although I know a little bit superficially, I can't write SCRIPT well. Can you give me a reference program?
Or write a reference for me? It is really difficult to me for write SCRIPT, And its difficult format : (
Thank you!

Please find a guide on Script in our Software Reference Manual. You can also refer to AN2018-27 for examples. You can use any text editor to write Scrpit, which is a C-like language.
