Control Techniques UNI1401 Servo Drive

The Control Techniques UNI1401 is a 0.75 kW, three‑phase AC variable‑speed drive (UNIDRIVE M100 series) rated for 380/480 V, 50/60 Hz operation with a 3.2 A overload limit for 60 s. Common failure points in this class include overheating of the power MOSFET array, insulation breakdown between phase windings and the chassis, and degradation of the drive’s internal capacitors or protection diodes. Initial checks should verify that the input voltage is within spec and that the supply current does not exceed the 3 A rating; inspect the motor wiring for loose connections or damaged conductors; and review any fault codes displayed on the drive’s panel or via its communication interface.[oss-gpt-20b] Post Comment
