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.
Input voltage too high for three phase A.C. input. The manual's first action is: “Check the input voltage of three phase A.C.”
Self-checking circuit error of sampling Phase-U current occurs due to strong interference, abnormal hall components, or abnormal drive board. The manual's first action is: “Seek technical support”
Hardware overcurrent occurs from current loop value (PI) being too large. The manual's first action is: “1.Adjust the parameters of PI, and reduce Kp (CI.00、CI.02) 2.Check the motor insulation or line-to-ground insula…
Hardware overvoltage happens when voltage is too high. The manual's first action is: “1.Check the input A.C. voltage 2.Reduce the brake resistance value 3.Check the wiring of brake resistor 4.Increase the speed-reduci…
Over-heated Heatsink occurs due to high ambient temperature. The manual's first action is: “1.Check the input A.C. voltage 2.Reduce the brake resistance value 3.Check the wiring of brake resistor 4.Increase the speed-…
Software undervoltage happens from three-phase A.C. device instant outage, loose input power wires, or power cut-off and drive discharge. The manual's first action is: “1.Check the wiring 2.Check whether it's instant …
NTC's temperature anomaly occurs due to abnormal NTC temperature. The manual's first action is: “Seek for technical support”
CD.00 (DC link controller setting value) is wrong when CD.00 must be bigger than PU.17 (Brake voltage). The manual's first action is: “Adjust CD.00 value”
Power board fails due to power board abnormality. The manual's first action is: “Seek for technical support”
CAN bus communication is wrong because baud rate is incorrectly set or electromagnetic interference is too large. The manual's first action is: “1. Check the baud rate setting 2. Check the grounding, eliminate the int…
Error setting of motor model DR.01 occurs due to unconnected communication lines, loose connections, internal circuit abnormality, or missing motor model setup. The manual's first action is: “1. Check the wiring 2. Se…
Non-finished self-searching notch position happens when former notch position self-searching hasn’t finished. The manual's first action is: “Clean the error, do notch position searching once again”
Key operation error occurs when pressing RUN or STOP keys while drive is enabled by terminal. The manual's first action is: “Clear the error message , run the drive again”
Pressure sensor disconnection happens when the pressure sensor line is loose or not connected. The manual's first action is: “Check the wiring”
Over-heated Heatsink occurs due to high ambient temperature, surrounded heated objects, or cooling fan stopping. The manual's first action is: “1.Check whether the ambient temperature is too high.”
