How can we help?

Join the controller's Wi-Fi access point (default PW-AP-1, password SpeedControl) and browse to http://192.168.50.1 — or type http://pw.setup, which resolves to the same address. The config UI is served locally from the controller, not the internet, so your phone or laptop must stay on the controller's network; if it warns about “no internet connection”, stay connected anyway.

If you've changed the access point name or password in Settings, use your values. More in the documentation hub.

No. The browser flasher writes only the application and web-interface partitions — it never touches the bootloader region and never erases the whole chip. An interrupted write leaves the bootloader intact, so reconnect over USB and flash again. An incomplete application image simply won't boot, and the motor stays off until a good image is flashed.

That's the protection doing its job — launching from a standstill draws stall current, which is what trips the surge or impulse tier. By default each channel allows 100 A continuous, 150 A surge for 2 s, and 200 A impulse. Before raising any threshold, try slowing the throttle ramp-up in your drive profile — a gentler ramp absorbs most launch transients without losing torque feel. The tiers and defaults are in the fault reference; if the motor's locked-rotor current is genuinely above those limits, the controller is undersized for the application.

No. The access point is for configuration and diagnostics only — the control loop, limits, and protections run entirely on-board, so connecting or disconnecting a phone or laptop has no effect on throttle, braking, or safety behavior. The status LED shows the difference: solid means no device is connected, a slow blink means one is (see the fault & LED reference).

No — configuration lives in its own storage partition, which neither update path touches. The browser flasher writes only the application and web-interface images and never erases the chip; OTA updates from the web UI behave the same. OTA requires the controller's access point password and a matching pair of application and web-interface images from the same release package — the upload is rejected if the versions don't match.

The DRV1100 series drives brushed DC motors; brushless (BLDC/FOC) motors are not supported. Out of the box the protections default to a 16 V undervoltage trip, an 86 V overvoltage trip, and 100 A continuous per channel (150 A surge, 200 A impulse) — all adjustable in the web UI (see the fault reference). The hard electrical limits for your board revision are in the datasheet.
