4.3
When the motor ramps to stop, the deceleration time is longer. When setting this param-
eter to 2 with auto acceleration/deceleration, the deceleration will be quicker.
P0822
This parameter sets the DC link voltage at which the brake chopper is activated.
The maximum value depends on the b maXX
®
used, up to 430.0 V
DC
for single-phase
devices and up to 860.0 V
DC
for three-phase devices.
This parameter is invalid for b maXX
®
BM1x1x models without brake chopper.
P0823
The drift current will occur in a specific zone of the motor and it will make motor instable.
By using this parameter, it will improve this situation greatly.
The drift current zone of the high-power motors is usually in the low frequency area.
It is recommended to set to more than 2.0.
