6 - VECTOR REGULATION MODE
6 - 14 GV3000/SE 49'1329 e
For SVC operation (U.001 = SE):
As the max. field weakening range (U.005/U.017) is 1:2 , the highest setting is two
times the synchronous speed:
Top speed =
U.002
U.003 * 120 * 2
or
U.002
120 * 240
where sync. Speed =
U.002
U.003 * 120
ATTENTION: The setting of parameters U.001 (Encoder PPR), U.002 (Motor
Poles), U.003 (Motor Nameplate Base Frequency), U.005 (Motor Nameplate
RPM), and U.017 (Motor Top Speed) determines the motor maximum speed.
Note that the drive limits the output frequency to the motor to 240 Hz.
•
Increasing this number above Motor Nameplate RPM (U.005) will increase the
field weakening range.
•
The range of the tunable parameter P.004 (Maximum Speed) is limited by the
value in U.017.
•
For applications not requiring constant horsepower operation, U.017 should be
set equal to U.005 (Motor Nameplate RPM).
If you change this parameter after performing self-tuning using parameter U.008,
you must repeat the self-tuning procedure.
U.018 Line Voltage
Parameter Range: 300 - 565 VAC
Default Setting: 400 VAC
Type: Configurable (in standby only)
Description: Phase to phase nominal line voltage provided to the drive input power terminals.
If the internal Braking Unit option is used, see also Section 2, Table 2-5, Note 1) of
Power units manual 49'1327.
Important : The value entered should not deviate more than +/-10% from actual line voltage.
U.019 Flux Current Regulator Proportional Gain
Parameter Range: 0.10 to 31.99
Default Setting: 0.3
Parameter Type: Tunable (at rest or during operation)
Refer to: U.020 Flux Current Regulator Integral Gain
Description: This parameter determines the performance of the magnetizing current regulator.
Higher values will increase dynamic response, but may reduce stability.
For most applications, it is recommended that this parameter is not be changed.
U.020 Flux Current Regulator Integral Gain
Adjustment Range: 40.0 to 628.0 radians/second
Default Setting: 50.0
Parameter Type: Tunable (at rest or during operation)
Refer to: U.019 Flux Current Regulator Proportional Gain
Description: As above for U.019.
