2. When the load of a certain drive is
heavy, the drive will automatically reduce
the output frequency appropriately
according to the parameters set by this
function to unload part of the load. This
value can be adjusted gradually from
small to large during debugging. The
relationship between load and output
frequency is shown in the following
figure:

Set range: 50.0%
～
180.0%
For the coefficient of voltage-frequency
ratio during deceleration, increase the
voltage-frequency ratio during
deceleration, in this case, the output
voltage increases and the deceleration will
be faster, which is good for quick stop
without reporting overvoltage.

When the output frequency is less than or
equal to the set value of this function
code, an indication signal is output (the
terminal outputs No. 10 function).

1. This group of functions is used to
realize the fixed-length stop function.
2. The drive inputs counting pulses from
DI5 (F6.19 needs to be set to 1), and
obtains the actual length according to the
number of pulses per revolution of the
speed measuring shaft (FC.13) and the
shaft circumference (FC.12).
