Not recommended. The K7’s overload rating is 110% for 60 seconds (variable torque), whereas constant torque drives (e.g., G7 or H7) provide 150% for 60 seconds. Using a K7 for a high-inertia conveyor will trip OC faults repeatedly.
Typically 380V to 480V AC (400V Class), 50/60 Hz . yaskawa k7 manual
Keep separate from signal cables to avoid noise. Grounding: Use a single-point ground to the control panel. Encoder Connection: Use shielded twisted-pair cables. Commissioning and Startup Not recommended
This is the manual’s MVP. It lists every error (CPF00, oC, Uv1, etc.) with three columns: Probable Cause , Corrective Action , and Related Parameters . For a "oV" (Overvoltage) fault, it tells you to check decel time (C1-02) and the braking resistor before blaming the power line. Typically 380V to 480V AC (400V Class), 50/60 Hz
