0 (diS): The drive does not take account of mains supply
breaks and continues to operate while there is sufficient
voltage on the DC bus.
1 (StOP):
In the event of a mains supply break, the drive will
decelerate on a ramp, automatically calculated by the drive,
so that the motor sends back the energy to the drive DC bus
and therefore continues to power its control electronics. On
returning to normal conditions, deceleration continues until
the motor stops, but according to the deceleration mode
configured in
2 2 . . 0 0 4 4 .
2 (rd.th): In the event of a mains supply break, the drive will
decelerate on a ramp, automatically calculated by the drive,
so that the motor sends back the energy to the drive DC bus
and therefore continues to power its control electronics. On
returning to normal conditions, the motor reaccelerates up to
the reference speed.

Factory setting
: 0
Used to choose one of 3 Run/Stop command and Direction of
rotation management modes.
0 (Lchd) : DI2 terminal used as FWD/Stop
DI3 terminal used as REV/Stop
Commands given by latched contacts.
1 (Puls) : DI2 terminal used as FWD
DI3 terminal used as Stop
DIO1 terminal used as REV
Commands given by pulsed contact.
In this mode, the DI4 input can be assigned by the customer
but only as a stay-put contact and the stop command via DI3
cannot be reassigned. To switch from FWD to REV or vice
versa, go via a stop command.
2 (r.InP) : DI2 terminal used as Run/Stop
DI3 terminal used to select the direction of
rotation.
Commands given by latched contacts.
These three configurations result in automatic assignment of
the digital inputs. If, within a configuration, an input is not used
by the application (no Reverse operation for example), the
corresponding input can be reassigned by means of menu 8.
Note: Modifications to 6 6 . . 0 0 4 4 must be made with the drive
disabled.

:Injection braking level
Adjustment range : 0 to 4 4 . . 0 0 7 7
Factory setting : 100.0%
This parameter defines the level of current used for DC
injection braking.
CAUTION:
For efficient braking, the value of parameter 6

should
be 60% minimum.
6.07
:Injection braking time
Adjustment range : 0 to 25.0 s
Factory setting
: 1 s
This parameter defines the DC injection braking time when
6 6 . . 0 0 1 1 is at 2, 3 or 4.
6.08
:Hold zero speed
Adjustment range : 0 or 1
Factory setting
: 0
0 (OFF): The drive output is deactivated at zero speed.
1 (On):
The drive output remains active at zero speed in order
to hold the torque at standstill. The drive output is deactivated
when
6 6 . . 0 0 8 8 changes to 0. While holding zero speed, the
display indicates "StoP".
Note : When the drive is in " Stop " state, and Run command
is not enabled after one minute, the drive changes back to
"rdy" state (drive output deactivated).
