5.19.2 - Explanation of parameters in menu 18
• Menu reserved for POWERDRIVE MD2R drives.
NB:
On products such as MD2R , the term «active rectifier» applies
to the converter connected to the mains, the term «inverter»
applies to the converter connected to the motor or generator.
Initialisation procedure for the serial link between the
active rectifier and the inverter in MD2R drives :
1- Drive powered down, connect the keypad or parameter-
setting interface to the active rectifier, power up the
POWERDRIVE .
- Set
11.66 = Regen rectifier (2).
- Check that 11.31 = Active rectifier on Main power (4) and
10.75
= Yes (1).
2- Power down the drive, connect the HMI to the inverter,
power it up again:
- Then set 11.66 = Regen inverter (1).
- Set 11.31 in the desired operating mode (Induction motor in
open loop mode (1), Induction motor in vector control mode (2),
or PM motor (Servo) in vector control mode (3)).
- Leave 10.75 = Yes (1).
3- Power down the drive, then power it up again.
- Enter the menu 18 settings in accordance with the application
requirements.

LEROY-SOMER contact.
18.01 : Reactive power
Adjustment range: ± 3200.00 kVA
Format: 32 bits
If the parameter is positive, the current is lagging the voltage.
If the parameter is negative, the current is leading the voltage.
18.02 : Active power
Adjustment range: ± 3200.00 kW
Format: 32 bits
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).
18.03 : DC bus voltage
Adjustment range: 0 to 1300 V
Format: 16 bits
Indicates the DC bus voltage measurement in Regen mode
only.
18.04
: Regen restart mode
Adjustment range : Synchro x3 (0), Synchro x1 (1),
Without synchro (2)
Factory setting : Synchro x1 (1)
Format: 8 bits
Defines the start mode when enabled.
Synchro x3 (0):
Three attempts to resynchronise. Then, in the event of failure,
the «Mains synchro» trip is generated.
Synchro x1 (1):
Only one attempt to synchronise. In the event of failure, the
«Mains synchro» trip is generated immediately.
Without Synchro (2):
Reserved.
18.05 : DC bus voltage set point
Adjustment range : 0 to 1300 V
Factory setting : T rating = 660 V, TH rating = 1070 V
Format: 16 bits
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
18.06 : Voltage loop proportional gain
Adjustment range: 0 to 32000
Factory setting: 1000
Format: 16 bits
18.07 : Voltage loop integral gain
Adjustment range: 0 to 32000
Factory setting: 20
Format: 16 bits
18.08 : Mains voltage
Adjustment range: 0 to 999 V
Format: 16 bits
This is the rms voltage at the Regen drive input.
18.09 : Mains frequency
Adjustment range: ± 400.0 Hz
Format: 16 bits
Indicates the mains frequency.
18.10 : Power feed forward compensation
Adjustment range: 0.00 to 100.00%
Factory setting: 0.00%
Format: 16 bits
This parameter can be used to reduce the transient voltages of
the DC bus in the event of load power impacts.
