Adjust Menu

ENGLISH

This menu can be accessed when the switch is in positions and . Adjustment parameters can be modified in stop mode OR during operation. Ensure that any changes made during

operation are not dangerous; changes should preferably be made in stop mode.

The list of adjustment parameters is made up of a fixed and a changeable part which varies according to :

-the selected macro-configuration

-the presence of an I/O extension card

-the reassignment of I/O

The following parameters can always be accessed in all the macro-configurations.

Code	Description		Adjustment range	Factory setting
LFr	Freq. Ref.	- Hz	LSP to HSP	–
	Appears when control via the display module is activated : LCC parameter in the control menu
ACC	Acceleration - s		0.05 to 999.9	3 s
dEC	Deceleration - s		0.05 to 999.9	3 s
	Acceleration and deceleration ramp times. Ranges 0 to motor nominal frequency (FrS)
AC2	Accelerate 2 - s		0.05 to 999.9	5 s
dE2	Decelerate 2 - s		0.05 to 999.9	5 s
	2nd acceleration ramp
	2nd deceleration ramp
	These parameters can be accessed if the ramp switching threshold (parameter Frt) is other than 0
	Hz or if a logic input is assigned to ramp switching.
LSP	Low Speed	- Hz	0 to HSP	0 Hz
	Low speed
HSP	High Speed	- Hz	LSP to tFr	50 / 60 Hz
				acc. to the switch
	High speed : ensure that this setting is correct for the motor and the application.
FLG	Gain	- %	0 to 100	20
	Frequency loop gain : used to adapt the rapidity of the machine speed transients according to the
	dynamics.
	For high resistive torque, high inertia or fast cycle machines, increase the gain gradually.
StA	Stability	- %	0 to 100	20
	Used to adapt the return to steady state after a speed transient according to the dynamics of the
	machine.Gradually increase the stability to avoid any overspeed.
ItH	ThermCurrent - A		0.25 to 1.36 In (1)	According to controller rating
	Current used for motor thermal protection. Set ItH to the nominal current on the motor rating plate.
tdC	DC Inj. Time - s		0 to 30 s Cont	0.5 s
	DC injection braking time.
	If this is increased to more than 30 s, "Cont" is displayed, permanent DC injection.
	The injection becomes equal to SdC after 30 seconds.

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