Mitsubishi Electronics FR-F700 Supply short circuit RS-485 terminals power Was shorted

	Function Name	Description	Indication
		Appears when a communication error between the PU and inverter occurred, the
	PU disconnection	communication interval exceeded the permissible time during the RS-485
		communication with the PU connecter, or communication errors exceeded the
		number of retries during the RS-485 communication.
	Retry count excess	Appears when the operation was not restarted within the set number of retries.
	Parameter storage devide	Appears when operation of the element where parameters stored became
	alarm	abnormal. (main circuit board)
	CPU error	Appears during the CPU and peripheral circuit errors.	/
			/
*5	Operation panel power	Appears when the RS-485 terminal power supply or operation panel power supply
failures	supply short circuit
	RS-485 terminals power	was shorted.
	supply short circuit
Major	24VDC power output short	Appears when terminals PC-SD were shorted.
	circuit
	Output current detection	Appears when output current exceeded the output current detection level set by the
	value exceeded	parameter.
	Inrush resistor overheat	Appears when the resistor of the inrush current limit circuit overheated.
	Communication error	Appears when a communication error occurred during the RS-485 communication
	(inverter)	with the RS-485 terminals.
	Analog input error	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.
	Internal circuit error	Appears when an internal circuit error occurred.
	Brake transistor alarm	This function stops the inverter output if an alarm occurs in the brake circuit, e.g.
		damaged brake transistors. In this case, the inverter must be powered off
	detection
		immediately. (Internal circuit error for the model 55K or less)

*1 Resetting the inverter initializes the internal thermal integrated data of the electronic thermal relay function.

*2 The error message shows an operational error. The inverter output is not shut off.

*3 Warnings are messages given before major failures occur. The inverter output is not shut off.

*4 Minor faults warn the operator of failures with output signals. The inverter output is not shut off.

*5 When major failures occur, the protective functions are activated to shut off the inverter output and output the alarms. *6 The external thermal operates only when the OH signal is set in Pr. 178 to Pr. 189 (input terminal function selection).
