KE600 Inverter Parameter Description
77
stronger electromagnetic interference.
If the carrier frequency is lower than the factory default, it is possible to cause less output torque of
motor and more harmonic current.
The effect of modifying carrier frequency is as following:
Carrier frequency

The inverter can automatically adjust the carrier frequency according to its temperature. This function can
reduce the possibility of overheat alarm of the inverter.

Acceleration time is the time of accelerating from 0Hz to ACC/DEC time reference frequency (P0-25).
Deceleration time is the time of decelerating from ACC/DEC time reference frequency (P0-25) to 0Hz.

There are totally four groups of acceleration/deceleration time which can be selected via the multifunctional
digital input terminals.
Group 1: P0-17, P0-18;
