P5.1.6
ab
Voltage at FWP
ID 290
Minimum value:
10.00%
Maximum value:
200.00%
Default value:
00.00%
Description:
Defines the voltage at the field weakening point, when the output frequency exceeds the field weakening point, the voltage will remain
constant.
P5.1.7
ab
V/Hz mid frequency
ID 291
Minimum value:
0.00 H
Maximum value:
FieldWeakPoint Hz
Default value:
VHzCurveMidFreqMFG
Hz
Description:
If the programmable V/Hz curve has been selected, this parameter defines the midpoint frequency of the curve. This value can be set
anywhere between 0 and the field weakening point. To either have a different V/Hz ramp or if set to the FWP, it will provide the field
weakening point voltage all the way up the curve.
P5.1.8
ab
V/Hz mid voltage
ID 292
Minimum value:
0.00%
Maximum value:
100.00%
Default value:
100.00%
Description:
If the programmable V/Hz curve has been selected, this parameter defines the mid-point voltage of the curve. This value can be set
anywhere between zero frequency volt and the field weakening point voltage.
P5.1.9
ab
Zero frequency voltage
ID 293
Minimum value:
0.00%
Maximum value:
40.00%
Default value:
0.00%
Description:
If the programmable V/Hz curve has been selected, this parameter defines the zero frequency voltage of the curve.
P5.1.10
b
Switching frequency
ID 288
Minimum value:
MinSwitchFreq kHz
Maximum value:
MaxSwitchFreq kHz
Default value:
DefaultSwitchFreqCT
kHz
Description:
Sets the switching frequency for the PWM output waveform.
P5.1.11
b
Sine filter enabled
ID 1665
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = Disabled; or
1 = Enabled.
Description:
This parameter enables the drive to have a fixed switching frequency which is required by some sine filters. The drive no longer
automatically adjusts the switching frequency based on the unit temperature.
P5.1.12
ab
Over voltage controller
ID 294
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
3
Options:
0 = Disable over voltage controller;
1 = The maximum controller output frequency is the (ramp fre 8 Hz);
2 = The maximum controller output frequency is the maximum frequency; or
3 = The maximum controller output frequency is the (maximum fre 8 Hz).
Description:
The over voltage control is used to limit the DC link voltage below the preset limit value. If over voltage control is enabled, the drive will
control the DC link voltage below the preset limit value by increasing the output frequency to allow the motor to use the energy.
P5.1.13
a
Over voltage controller reference
ID 1874
Minimum value:
DCLinkUnderVolt-
ResumeExcursion V
Maximum value:
DCLinkOverVoltBrake-
ChopperStartLimit V
Default value:
DCLinkRegenerating-
EnergyControlExcursion
V
Description:
The over voltage reference defines the preset limit value used in the overvoltage controller.
P5.1.14
b
Load drooping
ID 298
Minimum value:
0.00%
Maximum value:
100.00%
Default value:
0.00%
Description:
The drooping function enables speed drop as a function of load. This parameter sets that amount corresponding to the nominal torque
of the motor.
P5.1.15
b
Droop control filter time constant
ID 1630
Minimum value:
0 ms
Maximum value:
3,000 ms
Default value:
0 ms
Description:
Filter time when using droop control.
