5. Description of Function Codes
105
For high power frequency inverter, compensation mode 2 is recommended.
d6-05
Random PWM depth
Default
0
Setting Range
0: Random PWM invalid
1~10: Random PWM carrier frequency depth
The setting of random PWM depth can make the motor shrill noise to soft and reduce the electromagnetic
interference to other equipments. If this parameter is set to 0, random PWM is invalid.
d6-06
Current detected compensation
Default
5
Setting Range
0~100
SVC mode 0: Used in the application that high speed stability required.
SVC mode 1: Used in the application that high torque control linearity required.
d6-07
SVC mode selection
Default
1
Setting
Range
0
SVC mode 1
1
SVC mode 2
SVC mode 1: Used in the application that high speed stability required.
SVC mode 2: Used in the application that high torque control linearity required.
5.24 Group U0: Monitoring Parameters
Group U0 is used to monitor the frequency inverter's running state. You can view the parameter values by using
operation panel, convenient for on-site commissioning, or from the host computer by means of communication
(address: 0x7000 ~ 0x7044).
U0-00 ~ U0-31 are the monitoring parameters in the running and stop state defined by b9-02 and b9-03.
U0-00
Running frequency
Default
--
Display Range
0.00~320.00 Hz (b0-11 = 2)
U0-01
Setting frequency
Default
--
Display Range
0.00~3000.0 Hz (b0-11 = 1)
These two parameters display the absolute value of theoretical running frequency and set frequency. For the actual
output frequency of the frequency inverter, see U0-19.
U0-02
DC Bus voltage
Default
--
Display Range
0.0~3000.0 V
It displays the frequency inverter's DC bus voltage.
U0-03
Output voltage
Default
--
Display Range
0V~1140 V
It displays the frequency inverter's output voltage in the running state.
U0-04
Output current
Default
--
Display Range
0.00A~655.35 A (Frequency inverter power
≤ 55 kW)
0.0A~6553.5 A (Frequency inverter power > 55 kW)
