22 Control Optimization Parameters
22-00
DPWM switching upper limit frequency
Factory setting
8.00Hz
Setting range 0.00Hz
～
Maximum operating frequency
Only valid for V/f control.When the V/f is running, the wave transmission mode is lower than this value for the
7-segment continuous modulation mode, and the opposite is the 5-segment intermittent modulation mode.
In the 7-segment continuous modulation, the switching loss of the inverter is large, but the current ripple is small;
in the 5-step intermittent debugging mode, the switching loss is small and the current ripple is large; but it may
cause the motor at high frequency The instability of operation generally does not require modification.
For the V/f operation instability, please refer to parameter 03-11, for inverter loss and temperature rise, please
refer to parameter 00-10;

Dead zone compensation mode selection
Factory setting
1
Setting range
0
No compensation
1
Compensation mode 1
This parameter generally does not need to be modified. Only when there are special requirements on the quality
of the output voltage waveform, or when the motor exhibits abnormalities such as oscillation, it is necessary to try
to switch between different compensation modes. It is recommended to use compensation mode 2 for high
power.
22-03
Random PWM depth
Factory setting
0
Setting range
0
Random PWM is invalid
1~10
Random depth of PWM carrier frequency
Setting random PWM can make the monotonous harsh motor sound softer, and can help reduce external
electromagnetic interference. When the random PWM depth is set to 0, random PWM is invalid. Adjust the
random PWM to different depths to get different effects.
22-04
Fast current limit enable
Factory setting
1
Setting range
0
No enabling
1
Enabling
Enabling the fast current limit function can minimize the overcurrent fault of the inverter and ensure the
continuous operation of the inverter. If the inverter continues to be in the fast current limiting state for a long time,
the inverter may be damaged due to overheating, etc. This situation is not allowed.
Therefore, the inverter is used in the occasion of large current impact for a long time, please select 1, the rapid
current limit will alarm the fault CBC after a period of time, indicating that the inverter is overloaded and needs to
be stopped.
22-05
Current detection compensation
Factory setting
105
Setting range 100
～
110
It is used to set the current detection compensation of the inverter. If the setting is too large, the control
performance may be reduced. Generally no modification is required.
