Fault displayed	Probable cause		Procedure, remedy
PHF	•	speed controller incorrectly supplied or	•	check the power connection and the fuses
Mains Phase Loss		fuses blown	•	reset
	•	transient fault on one phase	•	configure the "In Phase Loss" (code
	• use on a single phase supply of an			IPL) fault to "No", in the FAULT menu
		ATV58•U72M2, U90M2 or a D12M2
		(3-phase)
USF	•	line supply too low	•	check the line voltage
Undervoltage	•	transient voltage dip
	•	damaged load resistor	•	change the load resistor
OSF	•	line supply too high	•	check the line voltage
Overvoltage
OHF	•	heatsink temperature too high	•	monitor the motor load, the speed
Drive Overheat		(tHd>118 %)		controller ventilation and wait for it to
				cool down before resetting
OLF	•	thermal trip due to prolonged overload	•	check the thermal protection setting,
Mot Overload		(tHr>118 %)		monitor the motor load
			•	a reset will be possible after approximately
				7 minutes
ObF	•	braking too sudden or driving load	•	increase the deceleration time, add a
Overbraking	•	supply overvoltage during operation		braking resistor if necessary
			•	check the possible supply overvoltage
OPF	•	one phase cut at the speed controller	•	Check the motor connections and the
Motor Phase Loss		output		operation of the output contactor (if fitted)
			•	If a motor starter is used in macro
				configuration, check the configuration of
				the relay R2 and the output contactor
LFF	•	loss of the 4-20mA setpoint on input AI2	•	check the connection of the setpoint
Loss Follower				circuits
OCF	•	ramp too short	•	check the settings
Overcurrent	•	inertia or load too high	•	check the size of the motor/speed
	•	mechanical locking		controller/load
			•	check the state of the mechanism
SCF	•	short-circuit or grounding at the speed	•	check the connection cables with the
Short Circuit		controller output		speed controller disconnected, and the
				motor insulation. Check the speed
				controller transistor bridge
CrF	•	load relay control fault	•	check the connectors in the speed
Precharge Fault	•	damaged load resistor		controller and the load resistor
SLF	•	incorrect connection on the speed	•	check the connection on the speed
Serial Link Flt		controller terminal port		controller terminal port
OtF	•	motor temperature too high (PTC	•	check the motor ventilation and the ambi-
Motor Overheat		probes)		ent temperature, monitor the motor load
			•	check the type of probes used
tSF	•	incorrect connection of probes to the	•	check the connection of the probes to
PTC Therm Sensor		speed controller		the speed controller
			•	check the probes
