Configuration Mode (ConF)
S1A28692 03/2010 157
Parameters described in this page can be accessed by:
(1) The parameter can also be accessed in the [SETTINGS] (SEt-) menu.
(2) Range 0.01 to 99.99 s or 0.1 to 999.9 s or 1 to 6,000 s according to [Ramp increment] (Inr) page 155
.
brA [Dec ramp adapt.]
[Yes] (YES)
CAUTION
RISK OF DAMAGE TO THE MOTOR
Choose only [Dec ramp adapt.] (brA) = [Yes] (YES) or [No] (nO) if the motor is a permanent magnet
synchronous motor, otherwise it will be demagnetized.
Failure to follow these instructions can result in equipment damage.
nO
YES
dYnA
Activating this function automatically adapts the deceleration ramp, if this has been set at a too low value according to the inertia
of the load, which can cause an overvoltage detected fault.
[Dec ramp adapt.] (brA) is forced to [No] (nO) if the brake logic control [Brake assignment] (bLC) is assigned (page 179
).
The function is incompatible with applications requiring:
- Positioning on a ramp.
- The use of a braking resistor (the resistor would not operate correctly).
[No] (nO): Function inactive
[Yes] (YES): Function active, for applications that do not require strong deceleration
The following selections appear depending on the rating of the drive and [Motor control type] (Ctt) page 92
. They enable
stronger deceleration to be obtained than with [Yes] (YES). Use comparative testing to determine your selection.
[High torq. A] (dYnA): Addition of a constant current flow component.
When [Dec ramp adapt.] (brA) is configured on [High torq. x] (dYnx), the dynamic performances for braking are improved
by the addition of a current flow component. The aim is to increase the iron loss and magnetic energy stored in the motor.

These parameters only appear if the corresponding function has been selected in another menu. When the parameters can
also be accessed and adjusted from within the configuration menu for the corresponding function, their description is detailed
in these menus, on the pages indicated, to aid programming.
T
Parameter that can be modified during operation or when stopped.
