Random PWM and carrier frequency
temperature adjustment inenabled.
2
Fixed PWM, and carrier frequency
temperature adjustment enabled.
3
Random PWM, and carrier
frequency temperature adjustment
enabled.
Two PWM carrier frequency adjustment modes, fixed and random, are
provided. The random PWM motor noise has wide frequency range, while
the fixed PWM motor noise has fixed frequency.
When the carrier wave temperature adjustment is enabled, the driver can
automatically adjust the carrier frequency according to its temperature. This
function can reduce the possibility of over heat alarm of the driver.

Speed-up time 1 refers to the time “t1” required for the driver to accelerate
from 0Hz to the maximum output frequency (F0-10).
Speed-down time 1 refers to the time “t2” required for the driver to decelerate
from the maximum output frequency (F0-10) to 0Hz,
as shown in the following figure:
