Code	Description	Adjustment range	Factory setting
FFt	TripThreshNST-Hz	0 to HSP	0 Hz

Freewheel stop trip threshold: When a stop on ramp or fast stop is requested, the type of stop selected is activated until the speed falls below this threshold. Below this threshold, freewheel stop is activated. This parameter can only be accessed if the R2 relay is not assigned to the “BLC: Brake Logic” function, and if an “on ramp” or “fast” type stop has been selected in the drive menu.

bIP Brake impul. No - Yes No

Brake release pulse

Yes : While the brake is released the torque is always in the FW (foward) control corresponds to the direction, regardless of the direction requested.

Check that the motor torque direction for FW (foward) control corresponds to the direction of increase in load; if necessary reverse 2 motor phases.

no : while the brake is released the torque is in the requested direction of rotation.

dtS Tacho Coeff. 1 to 2 1

Multiplication coefficient of the feedback associated with tachogenerator function :

	dtS =		9
		tacho voltage at HSP HSP
rPG	PI Prop.Gain			0.01 to 100	1
	Proportional gain of the PI regulator
rIG	PI Int.Gain			0.01 to 100/s	1 / s
	Integral gain of the PI regulator
FbS	PI Coeff.			1 to 100	1
	PI feedback multiplication coefficient
PIC	PI Inversion			No - Yes	No
	Reversal of the direction of correction of the PI regulator
	no : normal yes : reverse
Ftd	Freq.Lev.Att- Hz			LSP to HSP	50/60 Hz
	Motor frequency threshold above which the logic output changes to 1
F2d	Freq.Lev.2 - Hz			LSP to HSP	50/60 Hz
	Same function as Ftd, for a second frequency value
Ctd	Curr.Lev.Att-		A	0 to 1.36 In (1)	1.36 In (1)
	Current threshold above which the logic output or the relay changes to 1
ttd	ThermLev.Att-		%	0 to 118%	100%
	Motor thermal state threshold above which the logic output or the relay changes to 1
tL2	Trq.Limit 2		- %	0 to 200% (2)	200%
	Second torque limit level activated by a logic input

(1)In corresponds to the speed controller nominal current indicated in the catalog and on the speed controller identification label for "high torque" applications.

(2)100% corresponds to the nominal torque of a motor with a power rating equal to that associated with the speed controller for "high torque" applications.

Parameters in gray boxes appear if an I/O extension card is installed
