I lim. Adapt
No-Yes No
Adaptation of the current limit according to the output frequency.
This parameter only appears in the "variable torque" VT macro-configuration (ventilation
applications where the load curve changes according to the density of the gas).

DecRampAdapt
No-Yes No
Activation of this function is used to increase the deceleration time automatically if this has been set
to too low a value for the inertia of the load, thus avoiding an ObF fault.
This function may be incompatible with positioning on a ramp and with the use of a braking resistor.
The factory setting depends on the macro-configuration used :
No for handling, Yes for variable torque and general use.
If relay R2 is assigned to the brake sequence function, the parameter brA remains locked on No.

SwitchRamp2- Hz
0 to HSP 0 Hz
Ramp switching frequency.
Once the output frequency exceeds Frt, the ramp times taken into account are AC2 and dE2.

Type of stop
STN - FST - NST - DCI STN
Type of stop:
When a stop is requested, the type of stop is activated until the Ftt threshold (adjust menu) is
reached.
Below this threshold, freewheel stop is activated.
Stn: On ramp
Fst: Fast stop
Nst: Freewheel stop
Dci: DC injection stop
This parameter cannot be accessed if the R2 relay is assigned to the “BLC: Brake Logic” function.
