F8.24 Droop control
0.00~10.00Hz
【 0.00Hz 】
When several motors drive the same load, each
motor's load is different because of the difference
of motor's rated speed. The load of different
motors can be balanced through droop control
function which makes the speed droop along with
load increas e . When the motor outputs rated
torque, actual frequency drop is equal to F 8.24.
User can adjust this parameter from small to big
gradually during commissioning. The relation
between load and output frequency is in the
following figure.
