Value Range Description
F2-21
Maximum output voltage
coefficient
105% 100% to 110%
Indicates the boost capacity on the basis of maximum voltage of
the AC drive.
Increasing F2-21 improves the maximum loading capacity in
motor field-weakening range, but increases motor current ripple
and motor temperature. Decreasing F2-21 weakens the maximum
loading capacity in motor field-weakening range, but reduces
motor current ripple and motor temperature. Generally, this
parameter needs no adjustment.
