			Table D — Alarm Codes

	ALARM	ALARM NAME	DESCRIPTION AND RECOMMENDED CORRECTIVE ACTION
	CODE	IN PANEL	DESCRIPTION AND RECOMMENDED CORRECTIVE ACTION
	CODE	IN PANEL
	2001	—	Reserved

	2002	—	Reserved

	2003	—	Reserved

	2004	DIR LOCK	The change in direction being attempted is not allowed. Do not attempt to change the direction of motor rota-
	2004	DIR LOCK	tion, or Change parameter 1003 DIRECTION to allow direction change (if reverse operation is safe).

	2005		Field bus communication has timed out. Check fault setup (3018 COMM FAULT FUNC and 3019 COMM
	2005	I/O COMM	FAULT TIME). Check communication settings (Group 51 or 53 as appropriate). Check for poor connections
			and/or noise on line.
	2006	AI1 LOSS	Analog input 1 is lost, or value is less than the minimum setting. Check input source and connections. Check
	2006	AI1 LOSS	the parameter that sets the minimum (3021) and the parameter that sets the Alarm/Fault operation (3001).

	2007	AI2 LOSS	Analog input 2 is lost, or value is less than the minimum setting. Check input source and connections. Check
	2007	AI2 LOSS	parameter that sets the minimum (3022) and the parameter that sets the Alarm/Fault operation (3001).

			Panel communication is lost and either the VFD is in local control mode (the control panel displays HAND), or
	2008		the VFD is in remote control mode (AUTO) and is parameterized to accept start/stop, direction or reference
	2008	PANEL LOSS	from the control panel. To correct, check the communication lines and connections, Parameter 3002 PANEL
			LOSS, and parameters in groups 10 COMMAND INPUTS and 11 REFERENCE SELECT (if drive operation
			is REM).
	2009	—	Reserved

	2010		Motor is hot, based on either the VFD estimate or on temperature feedback. This alarm warns that a Motor
	2010	MOT OVERTEMP	Overload fault trip may be near. Check for overloaded motor. Adjust the parameters used for the estimate
			(3005 through 3009). Check the temperature sensors and Group 35 parameters.
	2011		Motor load is lower than expected. This alarm warns that a Motor Underload fault trip may be near. Check
	2011	UNDERLOAD	that the motor and drive ratings match (motor is NOT undersized for the drive). Check the settings on param-
			eters 3013 to 3015.
	2012	MOTOR STALL	Motor is operating in the stall region. This alarm warns that a Motor Stall fault trip may be near.

	2013*	AUTORESET	This alarm warns that the drive is about to perform an automatic fault reset, which may start the motor. To
	2013*	AUTORESET	control automatic reset, use parameter group 31 (AUTOMATIC RESET).

	2014*	AUTOCHANGE	This alarm warns that the PFA autochange function is active. To control PFA, use parameter group 81 (PFA)
	2014*	AUTOCHANGE	and the Pump Alternation macro.
			and the Pump Alternation macro.
	2015	PFA INTERLOCK	This alarm warns that the PFA interlocks are active, which means that the drive cannot start any motor (when
	2015	PFA INTERLOCK	Autochange is used), or a speed regulated motor (when Autochange is not used).

	2016	—	Reserved
	2017*	OFF BUTTON	This alarm indicates that the OFF button has been pressed.
	2018*		This alarm warns that the PID sleep function is active, which means that the motor could
	2018*	PID SLEEP	accelerate when the PID sleep function ends. To control PID sleep, use parameters
			4022 through 4026 or 4122 through 4126.
	2019	ID RUN	The VFD is performing an ID run.
	2020	OVERRIDE	Override mode is activated.
	2021	START ENABLE 1	This alarm warns that the Start Enable 1 signal is missing. To control Start Enable 1 function, use parameter
	2021	MISSING	1608. To correct, check the digital input configuration and the communication settings.
		MISSING
	2022	START ENABLE 2	This alarm warns that the Start Enable 2 signal is missing. To control Start Enable 2 function, use parameter
	2022	MISSING	1609. To correct, check the digital input configuration and the communication settings.
		MISSING
	2023	EMERGENCY STOP	Emergency stop is activated.

*This alarm is not indicated by a relay output, even when the relay output is configured to indicate alarm conditions, parameter 1401 RELAY OUT- PUT = 5 (ALARM) or 16 (FLT/ALARM).

Check the heat sink as follows (when necessary):

1.Remove power from drive.

2.Remove the cooling fan.

3.Blow clean compressed air (not humid) from bottom to top and simultaneously use a vacuum cleaner at the air outlet to trap the dust. If there a risk of the dust entering adjoining equipment, perform the cleaning in another room.

4.Replace the cooling fan.

5.Restore power.

Table E — Maintenance Intervals
