P9 . 02
Motor overload warning
coeffcient
This function is used to give a warning signal to the control system
via M01 before motor overload protection. This parameter is used to
determine the percentage, at which pre-warning is performed before
motor over1oad. The larger the value is, the less advanced the pre­
warning will be.
When the accumulative output current of the AC drive is greater
than the value of t.he overload inverse time-lag curve multiplied by
P9.02, the multifunction digital M01 terminal on 1he AC drive (Motor
overload pre-warning) becomes ON.

P9. 0 4
Overvoltage stall protective
voltage
When the DC bus voltage exceeds the value of P9.04 (Overvoltage
stall protective voltage) during deceleration of the AC drive, the AC
drive stops deceleration and keeps the present
running frequency. After the bus voltage declines, the AC drive
continues to decelerate. P9.03 (OVervo!tage stall gain) is used to
adjust the overvoltage suppression capacity of the AC drive. The
larger the value is, the greater the overvoltage suppression capacity
be.
will
In the prerequisite of no overvoltage occurrence, set P9.03 to a
small value.
For small-inertia load, the value should be small. otherwise, the
system dynamic response will be slow. For large-inertia load, the
value should be large. Otherwise, the suppression result will be poor
and an overvoltage fault may occur.
set to 0, the overvoltage stall function is disabled.
