5.19.2 - Explanation of parameters in menu 1 8
Before changing settings in menu 18:
- Connect the HMI to the rectifier
- Set
11.66
= Rectif.REGEN (2)
- Make sure that
11.31
= REGEN (4) and that
10.75
= YES (1)
- Connect the HMI to the inverter
- Then set
11.66
= Invert. REGEN (1)
- Set
11.31
to the desired operating mode (open loop ,
closed loop , or servo )
- Leave
10.75
= YES (1)
- Power down the drive, then power it up again
- Then configure menu 18
For any further information, please get in touch with your
usual LEROY-SOMER contact.
: Reactive power
Adjustment range :
If the parameter is positive, the current is lagging the voltage.
If the parameter is negative, the current is leading the voltage.
: Active power
Adjustment range :
18.02
is the absorbed active power measured by the drive.
If this parameter has been assigned to an analog output via
menu 7, 10 V corresponds to the maximum power measurable
by the drive (I max = 150% of drive rated current).
: DC bus volta g e in Re g en mode
Adjustment range : 0 to 1300 V
Indicates the DC bus voltage measurement in Regen mode
only.
: Re g en restart mode
Adjustment range : Synchro x3 (0), Synchro x1 (1),
NO Synchro (2)
Factory setting : Synchro x1 (1)
Defines the start mode when enabled.
Synchro x3 (0): Three attempts to resynchronise. Then, in
the event of failure, the "Mains synchronisation" trip is
generated.
Synchro x1 (1): Only one attempt to synchronise. In the
event of failure, the "Mains synchronisation" trip is
g enerated immediately.
NO Synchro (2): Function not available in the current
version.
: DC volta g e set point
Adjustment range : 0 to 1300 V
Factory setting
: T: 660 V, TH: 1070 V
The sinusoidal rectifier sets the DC bus to the level specified
by this parameter. The bus voltage must always be greater
than the supply voltage between phases x
—
2.
Recommended values:
Mains supply 400 V: 660 V
Mains supply 460 V: 740 V
Mains supply 480 V: 760 V
Mains supply 690 V: 1070 V
: Volta g e loop proportional g ain
Adjustment range : 0 to 32000
Factory setting
: 1000
: Volta g e loop inte g ral g ain
Adjustment range : 0 to 32000
Factory setting
: 20
: Mains volta g e
Adjustment range : 0 to 999 V
This is the rms voltage at the Regen drive input.
: Mains fre q uency
Adjustment range : ± 590.0 Hz
Indicates the mains frequency.
: Power feed forward compensation
Adjustment range : 0.00 to 100.00%
Factory setting
: 0.00%
This parameter can be used to reduce the transient voltages
of the DC bus in the event of load power impacts.
: Current offset
Adjustment range : ± 300.0%
Factory setting
: 0.0%
This parameter is used as the active current reference when
the drive is configured for current control (
18.28
). Specify a
positive reference for the power to be absorbed from the
mains supply to the drive and a negative reference for the
power to flow from the drive to the mains supply.
: Reactive reference current
Adjustment range : ±
04.24
Factory setting : 0.0%
This parameter is used as the reactive current reference. With
a value of zero, the input power factor is around 1. A value not
equal to zero enables reactive current to be absorbed or
produced:
- If the parameter is positive, the absorbed current will lag the
supply voltage
- If the parameter is negative, the absorbed current will lead
the supply voltage
