What to do if Mitsubishi Electric F700 shows fin overheat?
If your Mitsubishi Electric Inverter displays a fin overheat error, it means the heatsink has overheated, triggering the temperature sensor to shut off the inverter output. Here's what you can do: 1. Ensure the ambient temperature is within the specified limits. 2. Clean the heatsink to remove any dust or obstructions. 3. Consider replacing the cooling fan.
What to do if Mitsubishi Electric F700 Inverter shows input phase failure?
If your Mitsubishi Electric Inverter shows an input phase failure alarm, it means that when the function valid setting (=1) is set in Pr. 872 Input phase failure protection selection, one phase of the three phase power input opens. You can try the following: * Check and properly wire the cables. * Repair any breaks in the cable. * Verify the Pr. 872 Input phase failure protection selection setting.
Why Mitsubishi Electric Inverter shows regenerative overvoltage shut-off during acceleration?
If a regenerative overvoltage shut-off occurs during acceleration with your Mitsubishi Electric Inverter, it indicates that regenerative energy is causing the inverter's internal main circuit DC voltage to exceed the specified value, activating the protective circuit. To resolve this: * Decrease the acceleration time. * Utilize the regeneration avoidance function (Pr. 882 to Pr. 886).
What to do if Mitsubishi Electric F700 displays fan fault?
If your Mitsubishi Electric Inverter displays a fan fault, it signifies that the cooling fan has stopped due to a fault or operates differently from the setting of Pr. 244 Cooling fan operation selection. Check for a fan fault and please contact your sales representative.
Why Mitsubishi Electric F700 shows regenerative brake prealarm?
The regenerative brake prealarm on your Mitsubishi Electric Inverter appears when the regenerative brake duty reaches or exceeds 85% of the Pr. 70 Special regenerative brake duty value. To address this: * Increase the deceleration time. * Check the Pr. 30 Regenerative function selection and Pr. 70 Special regenerative brake duty values.
Why Mitsubishi Electric Inverter shows regenerative overvoltage shut-off during constant speed?
If regenerative overvoltage shut-off occurs during constant speed with your Mitsubishi Electric Inverter, it means regenerative energy is causing the inverter's internal main circuit DC voltage to exceed the specified value, activating the protective circuit. Keep the load stable to resolve this.
What to do if Mitsubishi Electric F700 shows stall prevention?
If the frequency has fallen to 0.5Hz by stall prevention operation and remains for 3s, an alarm (E.OLT) appears to shutoff the Mitsubishi Electric Inverter output. Reduce the load weight.
Why Mitsubishi Electric F700 displays parameter write error?
A parameter write error on your Mitsubishi Electric Inverter can occur due to a few reasons: 1. You attempted to perform a parameter copy write during operation. After stopping operation, make parameter copy again. 2. An error occurred in the EEPROM on the operation panel side during parameter copy writing. Check for an operation panel (FR-DU07) failure. Please contact your sales representative.
What causes communication error on Mitsubishi Electric F700?
A communication error on your Mitsubishi Electric Inverter occurs when communication errors happen consecutively for more than the permissible retry count. This happens when a value other than "9999" is set in Pr. 335 RS-485 communication retry count during RS-485 communication from the RS-485 terminals. Perform wiring of the RS-485 terminals properly.
What does analog input error mean on Mitsubishi Electric Inverter?
An analog input error on your Mitsubishi Electric Inverter appears when 30mA or more is input, or a voltage (7.5V or more) is input with the terminal 2/4 set to current input. Either give a frequency command by current input or set Pr. 73 Analog input selection or Pr. 267 Terminal 4 input selection.
