Ergotech Erw300n Driver [upd]

Deep features — ErgoTech ERW300N driver

Firmware & tuning features

• Tunable PID loops for speed/position.
• Adaptive current limiting and temperature-based derating.
• Auto-phase/auto-calibration routines for sensorless commutation.
• Firmware modes: Configurable motion profiles, homing routines, and limit-switch handling.

For RS-485 (Multi-drop network)

• Set mode to RS-485 (Auto RTS control).
• Enable "Echo" suppression if you are daisy-chaining devices.

5.2 Micro‑stepping

• DIP switches (if the board is equipped with a 3‑position jumper block) – set the desired µstep resolution (binary weighting).
• UART command – 0xB2 <mode> where <mode> = 0 (full step), 1 (1/2), 2 (1/4)… up to 7 (1/128).
