Error, fault and alarm codes of products - what each code means, its causes and what to do - read from the manufacturers’ manuals, with the manual page each answer comes from.
Key operation error occurs when drive is enabled by terminal and RUN/STOP keys are pressed. The manual's first action is: “Clear error message , run the drive again”
Digital input ports have repetitive shortcut configurations. The manual's first action is: “Check values of DI.02 to DI.07, adjust values”
Incompletion of Z pulse searching because the previous search process hasn't finished. The manual's first action is: “Re-search the Z pulse”
Z pulse searching failure due to motor blockage, over-load, or alarm threshold adjustment. The manual's first action is: “1.Blockage of the motor 2.Over-loaded condition of the motor 3.Adjust the threshold alarm value…
Pressure sensor disconnection because its line is loose or not connected. The manual's first action is: “Check the wiring”
Zero sequence current exceeds threshold due to single-phase grounding or electromagnetic interference. The manual's first action is: “1.Check the electrical wiring and insulation 2.Seek technical support”
Motor reverse overspeed caused by too fast torque release or large speed loop parameters. The manual's first action is: “1.Increase torque release time (CS.22) 2.Modify the setting of speed loop, decrease Kp(CS00) or …
Initial angle searching fails from incorrect encoder settings or wrong motor wiring sequence. The manual's first action is: “1.Modify the setting of the encoder mode (EC.01 or EC.02 or DR.06) 2.Adjust the motor wiring…
Motor over-loaded due to excessive load. The manual's first action is: “Check the encoder (Dr.12) and do notch position self-searching again”
Motor overheated because the temperature sensor wiring is shorted, circuited, or loosened. The manual's first action is: “1.Check the temperature wirings 2.Check whether the internal motor is over heated or temperatur…
Heatsink temperature is too low, likely due to ambient temperature being too low. The manual's first action is: “Check the temperature wirings 2.Check whether the internal motor is over heated or temperature sensor wi…
Sampling Phase-W current circuit error due to strong interference, abnormal hall components, or drive board fault. The manual's first action is: “Seek technical support”
Sampling Phase-V current circuit error due to strong interference, abnormal hall components, or drive board fault. The manual's first action is: “Seek technical support”
PU.02 setting is incorrect when DR.00=0 or exceeds limit value when DR.00=3. The manual's first action is: “When DR.00=0, Reset PU.02 0-PU.02Smin(PU.12,DR.19) When DR.00=3, Adjust PU.02 or PU.03.”
Power-on self test fails due to short circuit, line-to-ground connection, or motor/internal wiring disconnects. The manual's first action is: “1.Check the wiring 2.Seek technical support”
