gefran SIEIDrive ADL300 Functions Description And Parameters List

ADL300 • Functions description and parameters list 85
Example:
Motor running driven by load. When the drive is enabled and the DC braking command is sent the direct current injection
phase is activated. When the command is enabled after the delay congured in PAR 3154 DC brake delay direct current
injection starts. PAR 3156 DC brake time is used to congure the duration of the injection phase and PAR 3158 DC brake
curr is used to congure the intensity of the injection phase current.
If the command is an impulse shorter than the time programmed with PAR 3156 DC brake time, the direct current injection
phase continues at least for the time set in parameter DC brake time.
If the command is an impulse longer than the time programmed with 3156 DC brake time, the direct current injection
phase continues for as long as the command is present.
In “OnCmd & AtStop” modes the direct current injection phase is executed when one of the two conditions described in
the “At stop” or “On command” modes is present
Menu PAR Description UM Type FB BIT Def Min Max Acc Mod
20.2.3 3154 DC brake delay s FLOAT 0.0 0.00 30.0 ERW FVS
This parameter is used to congure the delay in seconds between the moment DC braking is requested and the moment
direct current injection starts.
This delay enables the motor to demagnetize, and thus avoid an overcurrent due to the electromotive force of the motor
(e.f.m.).

20.2.4 3156 DC brake duration s FLOAT 1.0 0.01 30.0 ERW FVS
This parameter is used to congure the duration of direct current injection in the stator windings.
Menu PAR Description UM Type FB BIT Def Min Max Acc Mod
20.2.5 3158 DC brake current perc FLOAT 75.0 0.0 150.0 ERW FVS
This parameter is used to congure the value of the injected direct current.
This is expressed as a percentage of the rated current of the motor at full load (par. 488 Drive cont current).
Menu PAR Description UM Type FB BIT Def Min Max Acc Mod
20.2.6 3160 DC brake state ENUM 16BIT Non attivo 0 1 ER FVS
The status of direct current braking is displayed.
0 Not active
1 Active
Note! During braking the Enable command must be enabled. If this command is not present or is removed during the braking process, the drive
blocks the inverter bridge and the motor stops due to inertia, without braking.
During the direct current injection phase the Run command should not be enabled. If the Run command is sent to the drive, the ramp output
starts following the set reference; direct current output is produced in any case. The moment the DC braking command is removed there is
immediately a speed step without performing a change in the ramp.
During the direct current injection phase, for the Jog command follow the instructions provided for the Run command.
20.3 - FUNCTIONS/MOTOR OVERLOAD
The overload control function provides integrator logic to protect the motor against thermal overload. This protection presents the
characteristic I²t behaviour and is an emulation of the thermal relay of the motor controlled by the ADL300 drive.
Menu PAR Description UM Type FB BIT Def Min Max Acc Mod
20.3.1 3200 Motor ovld enable BIT 0 0 1 ERW FVS
Enabling of the motor overload control.

20.3.2 3202 Motor ovld factor perc FLOAT 150.0 100.0 300.0 ERWS FVS
Setting of the motor overload value. Percentage value of the motor rated current (par. 2002 Rated current).
