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.
The inverter enters alarm-stop mode when an external digital input signal is received. The manual lists no action for this code.
Overload protection has been triggered due to IGBT internal temperature exceeding preset value. The manual lists no action for this code.
Overheat protection has been triggered due to excessive heat sink temperature or cooling fan failure. The manual lists no action for this code.
Output phase loss protection detected by the inverter. The manual lists no action for this code.
The inverter stops output when DC link bus voltage drops below undervoltage level The manual's first action is: “Stops the inverter output when the DC link bus voltage drops below the undervoltage level (200 VDC for 3…
Overvoltage protection has been triggered. The manual's first action is: “The inverter stops the inverter output upon detection of an overvoltage condition (400 VDC for 3-phase 200V, 800 VDC for 3-phase 400V series) i…
Overvoltage protection has been triggered during deceleration. The manual's first action is: “The inverter stops the inverter output upon detection of an overvoltage condition (400 VDC for 3-phase 200V, 800 VDC for 3-…
Overvoltage protection has been triggered during acceleration. The manual's first action is: “The inverter stops the inverter output upon detection of an overvoltage condition (400 VDC for 3-phase 200V, 800 VDC for 3-…
The inverter detects zero-phase current and stops output to prevent overcurrent from a ground fault. The manual's first action is: “Upon detection of zero-phase current in the output power, this function stops the inv…
Ground fault protection has been triggered due to a ground fault in the output circuit during constant speed operation. The manual's first action is: “Stops the inverter output to protect the inverter from overcurrent…
Short-circuit protection has been triggered during deceleration. The manual's first action is: “Stops the inverter output to protect the inverter from overcurrent due to a short-circuiting in the output circuit.”
Overcurrent protection has been triggered during acceleration. The manual's first action is: “Stops the inverter output to protect the inverter from an overcurrent resulting from overload.”
