B090: Dynamic braking usage ratio –
This parameter limits the amount of time the
inverter can use the dynamic braking accessory device without entering the Trip Mode.
Please refer to
“Dynamic Braking” on page 5–5
for more information on dynamic
braking accessories.
B130/B131:
Over-voltage LADSTOP Enable / Over-voltage LADSTOP Level –
The over-
voltage LADSTOP function monitors the DC bus voltage and actively changes the
output frequency profile to maintain the DC bus voltage within settable limits. Although
“LAD” refers to “linear acceleration / deceleration,” the inverter only “STOPs” the
deceleration slope so that regenerative voltage will not cause the DC bus to rise enough
to cause an over-voltage trip event. Note that acceleration is not affected.
