What does it mean when my Fuji Electric Inverter displays an option communications error?
This indicates that a communications error has occurred between the connected option card and the inverter.
How to fix a Fuji Electric Controller output phase loss?
To correct an output phase loss in your Fuji Electric Controller: * Measure the output current and replace the output wires if necessary. * Measure the output current and consider replacing the motor if needed. * Check if any screws on the inverter output terminals have become loose and tighten them to the recommended torque. * Ensure that you are not using single-phase motors, as they are not compatible.
What does it mean if my Fuji Electric Inverter displays a RS-485 communications error (COM port 1)?
A communications error has occurred during RS-485 communication.
What to do if Fuji Electric Controller shows memory error?
To address a memory error in your Fuji Electric Controller: 1. Initialize the function code data with H03 (= 1). After initialization, check if pressing the key releases the alarm. Revert the initialized function code data to their previous settings, then restart the operation. 2. Check if appropriate noise control measures have been implemented (e.g., correct grounding and routing of control and main circuit wires). Implement noise control measures. Revert the initialized function code data to their previous settings, then restart the operation. 3. Initialize the function code data by setting H03 to "1," then reset the alarm by pressing the key and check that the alarm goes on. If the issue persists, the control PCB (on which the CPU is mounted) is defective.
What should I do if my Fuji Electric Controller has an inverter internal overheat?
If your Fuji Electric Controller is experiencing an internal overheat: * Measure the ambient temperature and lower it by ventilating the panel where the inverter is mounted. * Visually check whether the internal fan is functioning normally and replace the internal fan if necessary. * Reduce the number of times the power is turned ON/OFF (guide: 1/hour or less).
What to do if Fuji Electric Controller shows option communications error?
To resolve an option communications error with your Fuji Electric Controller: * Check whether the connector on the option card is properly engaged with that of the inverter. Reload the option card into the inverter. * Check whether appropriate noise control measures have been implemented (e.g. correct grounding and routing of signal wires, communications cables, and main circuit wires). Implement noise control measures.
What does it mean when my Fuji Electric Inverter shows a heat sink overheat?
This means that the temperature around the heat sink has risen abnormally.
Why does my Fuji Electric Inverter show an inverter overload?
This means that the temperature inside the inverter has risen abnormally.
What does it mean if my Fuji Electric Inverter is showing an undervoltage error?
This indicates that the DC link bus voltage has dropped below the undervoltage detection level.
What does it mean when my Fuji Electric Inverter displays an overvoltage error?
This means the DC link bus voltage has exceeded the overvoltage detection level.
