Soft PWM Function Selection
Range
【0】:
Disable
【1】:
Soft PWM
11-02=1:Soft PWM
Soft
PWM control can improve the metal noise produced by the motor, more comfortable for the
human ear. At the same time, Soft
PWM also limits RFI noise to a minimum level. The default setting
of Soft
PWM control is disabled.
The maximum carrier frequency of soft PWM mode is 8kHz.
11-03
Automatic Carrier Lowering Selection
Range
【0】:Disable
【1】:Enable
If inverter detects overheating situation, carrier will be reduce automatically. When overheating
situation is removed, carrier will back to the value of 11-01.
When 11-03=0, carrier frequency operation will be set by 11-01.
When 11-03=1, carrier frequency is automatically lowered when the inverter temperature is
higher than the setting value, to reduce the heat loss and avoid the over-heat trip of inverter.

【0.00~2.50】Sec
The S curve function for acceleration / deceleration is used to reduce mechanical impact caused
by the load during momentary starting and stopping of the inverter. To use the S curve
function set the time for acceleration start point (11-04), acceleration end point (11-05),
deceleration start point (11-06) and deceleration end point (11-07). Refer to figure 4.3.85.
