Output Current Based Effective Switching Frequency Reduction
Effective Switching Frequency is automatically reduced based on motor load current
as follows:
All ACS260-04-09A5-4 models:
•
If 2606 = 12kHz, 16 kHz, 24 kHz, Effective switching frequency is reduced to 8 kHz
when motor current exceeds 10.45A (110% of the drive rated current). Switching
frequency will return to the value set in 2606 when motor current reduces below 7.6A
(80% of drive rated current)
•
If 2606 = 32kHz, Effective switching frequency is reduced to 8 kHz when motor current
exceeds 10.45A (110% of drive rated current). Switching frequency changes to 24 kHz
when motor current reduces below 7.6A (80% of drive rated current). Switching
frequency will return to the value set in 2606 when motor current reduces below 6.7A
(70% of drive rated current)
All other models:
•
Effective switching frequency is reduced to 8 kHz when motor current exceeds 140% of
the drive rated current. Switching frequency will return to the value set in 2606 when
motor current reduces below 110% of drive rated current.
