| Driver model | TR21N / TR22N |
|---|---|
| Drive current per phase | 1 A / phase (full), 2 A / phase (half) |
| Input power | Single‑phase AC 100‑240 V ±10 % 3 A 50/60 Hz |
| Dimensions (L×W×H) | 126 mm × 70 mm × 145 mm |
| Weight | 820 g |
| Operating temperature range | 0 °C ~ +40 °C |
| Over‑heat protection indicator | LED lights when internal plate > 80 °C |
The driver should be installed in an environment with a temperature between 0 °C and 40 °C.
Adjust the RUN switch; the factory default running current is set, and you can change it according to the motor’s specifications.
The O.H. LED lights when the internal heat‑sink temperature exceeds 80 °C, triggering over‑heat protection that stops the motor.
Use the 24 V side of the voltage‑selection switch for 24 V signals or switch to the 5 V side for 5 V signals.
