8.3 Troubleshooting
	Condition			Check Point
		1)		Main circuit inspection:
				☞ Is the input (line) voltage normal? (Is the LED in the inverter is lit?)
				☞ Is the motor connected correctly?
		2)		Input signal inspection:
				☞ Check the operating signal input to the inverter.
				☞ Check the forward and the reverse signal input simultaneously to the inverter?
	The Motor Does Not			☞ Check the command frequency signal input to the inverter.
		3)		Parameter setting inspection:
	Rotate
				☞ Is the reverse prevention (FU1-03) function set?
				☞ Is the operation mode (FU1-01) set correctly?
				☞ Is the command frequency set to 0?
			4) Load inspection:
				☞ Is the load too large or is the motor jammed? (Mechanical brake)
			5) Other:
				☞ Is the alarm displayed on the keypad or is the alarm LED lit? (STOP LED blinks)
	The Motor Rotates		☞ Is the phase sequence of the output terminal U, V, W correct?
	in Opposite		☞ Is the starting signal (forward/reverse) connected correctly?
	Directions
	The Difference		☞ Is the frequency reference signal correct? (Check the level of the input signal)
	Between the		☞ Is the following parameter setting is correct?
	Rotating Speed and			Lower Limit Frequency (FU1-24), Upper Limit Frequency (FU1-25), Analog Frequency Gain (I/O-1~10)
	the Reference is		☞ Is the input signal line influenced by external noise? (Use a shielded wire)
	Too Large
	The Inverter Does		☞ Is the acceleration/deceleration time is set too short a period of time?
	Not Accelerate or		☞ Is the load too large?
	Decelerate		☞ Is the Torque Boost (FU1-27, 28) value is too high that the current limit function and the stall prevention
	Smoothly			function do not operate?
	The Motor Current		☞ Is the load too large?
	is Too High		☞ Is the Torque Boost Value (manual) too high?
	The Rotating Speed		☞ Is the Upper Limit Frequency (FU1-25) value correct?
			☞ Is the load too large?
	Does Not Increase		☞ Is the Torque Boost (FU1-27, 28) value too high that the stall prevention function (FU1-59, 60) does not
				operate?
		1)		Load inspection:
	The Rotating Speed			☞ Is the load oscillating?
	Oscillates When the	2)		Input signal inspection:
	Inverter is			☞ Is the frequency reference signal oscillating?
	Operating.	3)		Other:
				☞ Is the wiring too long when the inverter is using V/F control? (over 500m)
