Option (**)	OPT	Option Fault	Fault at the internal option of the inverter.
		Inverter H/W	A fault signal is output when an error occurs to the control circuitry of the
HW-Diag	HW		inverter. There are the Wdog error, the EEP error, and the ADC Offset for this

Inv. OLT	IOLT	Inverter Overload	The inverter turns off its output when the output current of the inverter flows
			more than the rated level (150% for 1 minute, 200% for 0.5 seconds).
		Thermal Sensor	Inverter uses NC thermal sensor for detecting heat sink temperature. If this

MC Fail	MCF	Magnetic	This fault is displayed when input power is not applied or M/C inside the inverter
		contactor fault	becomes faulty.

To reset fault perform one of the following:

}Press RESET key on the keypad.

}Close RST-CM terminals.

}Cycle power to the inverter.
