g
ulation mode selector
Adjustment range : VOLTAGE (0) or CURRENT (1)
Factory setting
: VOLTAGE (0)
Sets the control mode of the Regen drive.
VOLTAGE (0): In this mode, the drive sets the volta
g
e at
the DC bus terminals to the reference specified in
18.05
.
CURRENT (1):
In this mode, the drive is controlled current-wise
by the value defined in
18.11
: This enables, for example, two
Regen inverters to operate simultaneously; a master sets the
voltage at the common DC bus terminals and a slave shares the
current reference with the master.
: Active ref current
Adjustment range : -300% to +300%
This parameter indicates the current reference for the drive in
regen mode, coming from the DC voltage regulation when
18.28
is in voltage regulation mode or from the current offset
18.11
when
18.28
is in current control mode. It is expressed
as a percentage of the regen rated current
18.26
. Output via
analog channel or serial link assigned to the current reference
of another regen, it can be used to operate two rectifiers in
tandem, the master controlling the DC bus voltage, and the
slave controlling the current reference
18.29
.
CAUTION:
This tandem operation re
q
uires the rectifiers to be
connected in a specific manner. Please consult
LEROY-SOMER.

enerative current limit enable
Adjustment range : Disabled (0) or Enabled (1)
Factory setting
: Disabled (0)
This parameter allows enabling the maximum regenerated
current set in

enerative current limit
Adjustment range : 0.0% to 300.0% (% nom active current)
Factory setting
: 150.0% (this level being safe if
18.30
is
enabled by error)
If
18.30
is enabled (1), this parameter sets the maximum
level of current regenerated to the network (from DC bus to
power supply). In this case,
18.19
becomes the maximum
current drawn by the motor (from power supply to DC bus).
If
18.30
is disabled (0),
18.31
has no effect.

Adjustment range : NO (0) or YES (1)
Indicates to the synchronous rectifier the start and stop order
in the case where the start order for the synchronous rectifier
is controlled automatically by the output inverter.

Adjustment range : NO (0) or YES (1)
Indicates to the input synchronous rectifier that the output
inverter bridge is tripped NO (0) or healthy YES (1).
