Parameter
Description
Set the bus regeneration voltage braking time threshold to release the capacitor charge to make the
bus voltage drop.
For 220V (S2/T2) models, the default value of the driver relief point:
370V
, the setting range is
350V
to 400V;
For 380V (T3) models, the default value for the drive relief point:
680V
, with a setting range of
660V
to 760V
.

Parameter
Description
In order to avoid frequent access to the bus relief, the number of frequent accesses to regenerative
braking can be effectively reduced by this function code. The value cannot be set too large, too large
can easily cause large fluctuations in the DC bus.

Parameter
Description
Set the bus voltage undervoltage point threshold, when the bus voltage is less than this value will
report an undervoltage fault.
For 220V (S2/T2) models, the default value for drive undervoltage fault:
180V
, with a setting range
of
160V to 220V
.
For 380V (T3) models, the drive undervoltage fault default:
380V
, with a setting range of
370V to
500V
.
