F0.07 Acceleration and deceleration characteristics parameter Setting range: 0~1
It is used to set the acceleration and deceleration characteristic parameter of
inverters (fratile binary system setting).
LED UNITS: setting of inverter’s acceleration and deceleration curve type.
（Refer to Figure 6-3.）
0: Straight line acceleration and deceleration
The inverter’s output frequency increases or decreases at fixed speed. For most
loads, this mode can be selected.
1: S curve acceleration and deceleration
The inverter’s output frequency increases or decreases at varying speed. This
function is mainly to reduce noise and ventilation at acceleration and deceleration
and reduce load impact at start and stop.

Carrier frequency
Setting range: 1.5 ~ 10.0 KHz
This parameter is to determine the switch frequency of inverter’s internal power
module.
The carrier frequency mainly influences the audio noise and heat effect during
running. When mute running is required, it is applicable to appropriately increase
the value of the carrier frequency, but the maximum load allowable for the inverter
may be somewhat reduced, accompanied by somewhat increase of interference of
the inverter to the outside world. For the circumstances where the motor wire is too
long, it may lead to leaking current between motor wires and between the wire and
the ground. When the ambient temperature is too high and the motor load is too
