1. The overvoltage stall protection
function detects the bus voltage during the
decelerating operation of the drive and
compares with the overvoltage stall point
defined by F7.00 (relative to the standard
bus voltage) and the overvoltage control
voltage defined by F7.01 (relative to the
bus voltage change rate), if the bus
voltage exceeds the overvoltage stall
point or the bus voltage change rate
exceeds the overvoltage control voltage,
the drive will adjust the deceleration time
to make the output frequency slow down.
2. Overvoltage stall gain, and overvoltage
stall integration time: Used to adjust the
drive's ability to suppress overvoltage
during deceleration. The larger the gain,
and the longer the integration time, the
stronger the ability to suppress
overvoltage, and the drive's deceleration
time becomes longer accordingly. So,
under the premise of no overvoltage, the
smaller the gain and the longer the
integration time, the better the
deceleration effect.
Note: When the set stall point is low, it
is suggested that the user shall increase
the deceleration time appropriately.
