A5.00
:
5-stage continuous modulation mode.
In 7-stage continuous modulation mode, inverter switch loss is relatively big, but current ripple is
small. In 5-stage continuous modulation mode, inverter switch loss is relatively small, but current ripple
is big. High frequency may lead to motor operation instability, generally there is no need of modification.
For VF operation instability please refer to F3.11. For inverter loss and temperature rise please
refer to F0.15.
A5.01
PWM modulation mode
Asynchronous modulation
0
0
☆
Synchronous modulation
1
This parameter is only valid for VF control mode. Asynchronous modulation refers to carrier
frequency that linear changes with output frequency, and ensure that the ratio of them (carrier ratio)
remains the same. Generally high output frequency is benefit for output voltage quality.
Generally, synchronous modulation is not needed at low frequencies ( below 100Hz), because the
ratio of carrier frequency and output frequency is relatively high,asynchronous modulation advantage is
more obvious.
When running frequency is greater than 85Hz, synchronous modulation is valid. And fixed as
asynchronous modulation mode when below this frequency.

Generally speaking , A5.02 needs not to be modified. Only when the output voltage waveform quality
has special requirements or motor appears abnormal phenomenon would users switch the compensation
mode.

0
☆
PWM carrier frequency random depth
1~10
Set the random PWM, monotonous and harsh electromagnetic noise can be changed to the
heterogeneous and soft, the external electromagnetic interference can be effectively reduced. 0
indicates that the PWM is invalid. Different random PWM depth represents different regulation effect.
