Motion Fault Limit not causing fault state

Hello,

We have a system using position control with a small stepper motor driving a worm screw, and there are no limit switches installed. This corresponds to closed loop mode 2.

I am having trouble configuring the FMO parameter as described here: https://granitedevices.com/wiki/Using_stepping_motor_with_IONI#Setting_up_closed_loop_mode_2

No matter how low I set the FMO value (even as low as 1), the driver does not trigger a fault when the motor is stalled (mechanically blocked for testing, velocity = 0).

Additionally, if a fault were to occur, what would be the corresponding fault location code? The information on this page is unclear on that matter: https://granitedevices.com/wiki/Fault_location

I should add that I set the FMO value via the Granity GUI.

Granity IONI settings are attached. Firmware is 1.7.21

Thank you.

Benjamin G
