Code	Description		Factory setting
tHt	ThermProType		ACL
	Defines the type of indirect motor thermal protection provided by the speed controller. If the PTC
	probes are connected to the speed controller, this function is not available. No thermal protection :
	NO: No Prot.
	Self-cooled motor (ACL) : the speed controller takes account of a derating depending on the rotation
	frequency.
	Force-cooled motor (FCL) : the speed controller does not take account of a derating depending on
	the rotation frequency.
LFL	LossFollower		No
	Used to enable the loss of 4-20 mA reference fault.
	This fault can only be configured if the min/max AI2 ref. parameters (CrL and CrH) are greater than
	3 mA, or if CrL>CrH,
	- No : no fault.
	- Yes : immediate fault.
	- STT : stop according to the parameter STT, without a fault restart on the return of the signal.
	- LSF : stop according to the parameter STT, drive shows a fault after stopping.
	- LFF : Force the speed to the value set by LFF.
	-	RLS : maintain the speed reached when the 4-20mA disappeared without a fault, restart on
		the return of the signal.
LFF	Flt. Speed 4-20		0
	Fallback speed in the event of the loss of the 4-20mA signal. Can be adjusted from 0 to HSP.
FLr	Catch On Fly		No
	Used to enable a smooth restart after one of the following events :
	- loss of line supply or simple power off
	- fault reset or automatic restart.
	- freewheel stop or injection stop with logic input
	- uncontrolled loss downstream of the speed controller
	Yes / No options.
	If relay R2 is assigned to the brake sequence function, the FLr parameter remains locked on No.
StP	Cont. Stop		No
	Controlled stop on a line phase loss. This function is only operational if parameter IPL is set to No.
	If IPL is set to Yes, leave StP in position No. Possible choices :
	No : locking on loss of line supply
	MMS : Maintain DC Bus : voltage for the speed controller control is maintained by the kinetic energy
	restored by the inertia, until the USF fault (undervoltage) occurs
	FRP : Follow ramp : deceleration following the programmed dEC or dE2 ramp until a stop or until
	the USF fault (undervoltage) occurs. This operation does not exist on ATV58•U09M2, U18M2,
	U29M2 and U41M2.
Sdd	RampNotFoll		Yes
	This function can be accessed if feedback via tachogenerator or pulse generator is programmed.
	When enabled, it is used to lock the speed controller, if a speed error is detected (difference
	between the stator frequency and the measured speed). Yes / No options.
EPL	External fault		Yes
	Defines the type of stop on externel fault:
	-	Yes: immediate fault
	-	LSF Stop+flt: stop according to the Stt parameter, then fault at the end of stopping
