Baldor MN1274 06/2001 installation manual Parameter

Code	Problem	Check
12	Over voltage fault	Bus over voltage condition occurred.
		If this occurs during high deceleration, a regeneration resistor
		might need to be installed. If a regeneration resistor is already
		installed check the wiring and if it has an adequate rating.
		Alternatively, try decreasing the Mint DECEL parameter.
		Check that the correct AC voltage is being supplied for the power
		rating of your MintDrive.
		Check for power input line disturbances (mains spikes) and fit a
		mains filter.
		Measure the actual input voltage being supplied to the MintDrive
		and check that it is within the specification.
		If the problem persists, contact Baldor Technical Support.
15	Under voltage fault	DC Bus Voltage has fallen below minimum threshold.
		If this occurs during acceleration then the load may be too great for
		the acceleration selected. Try reducing the value of the Mint ACCEL
		parameter.
		Check that the correct AC voltage is being supplied for the power
		rating of your MintDrive.
		If the fault occurs immediately after power-up, remove the
		regeneration resistor (if connected) and try again.
		Check for power input line disturbances (sags caused by start-up
		of other equipment).
		Measure the actual input voltage being supplied to the MintDrive
		and check that it is within the specification
		If the problem persists, contact Baldor Technical Support.
16	Overload	The current rating of the drive has been exceeded.
		Check the motor and feedback wiring.
		If this occurs·during high acceleration rates, decrease the Mint
		ACCEL parameter and/or reduce the motor load.
		Check the motor and load for excessive friction or improper
		operation such as a broken gear in a gearbox.
