Carrier Characteristic - Veichi Electric AC60 series Manual

Carrier frequency
1KHz
8KHz
15KHz
Below 3.7KW： When the carrier frequency is 6 KHz, rated current is the maximum
output current.
5.5KW-22KW：When the carrier frequency is 3 KHz, rated current is the maximum
output current.
30KW-75KW：When the carrier frequency is 2 KHz, rated current is the maximum
output current.
Above 93KW：When the carrier frequency is 1.5 KHz, rated current is the maximum
output current.
Tips : In order to obtain better control characteristics, the ration of the
carrier frequency to maximum frequency of the inverter is proposed not less
than 36. lf long-term work in the low frequency , frequency inverter are
proposed to reduce the carrier frequency to reduce the impact of the dead time

characteristic
LED 0 digit：correlative setting of carrier and output frequency
0：Output frequency correlation invalid
1：Output frequency correlation valid
When the correlation between carrier and output frequency is valid,
frequency inverter can auto-adjust the carrier frequency according to the
output frequency. This function can improve low frequency performance of the
frequency inverter, and can enhance torque. If cooperatively used with the
torque upgrade function, the low frequency permance will be more outstanding.
