The board supports two ways to control stepper drivers: "High-True" and "Low-True". You must choose the correct method based on your stepper driver's logic requirements: bsmce04u-pp manual

BSMCE04U-PP-TECH-001 Product Line: Power Protection / Motor Control Series Revision: 4.2 Connect to the VFD's analog voltage input terminal

Features a 0-10V analog output terminal (AVI) that interfaces directly with a Variable Frequency Drive (VFD) to adjust spindle RPM. You must choose the correct method based on

While the board supports 100kHz, many users find better stability at Motor Outputs:

Interrupting a firmware update bricks the unit. The manual warns that recovery requires an SPI programmer and a JTAG adapter (not user-serviceable).
