During deceleration,the inverter detects DC bus voltage and compares it with over-
voltage stall protection point.If DC bus voltage exceeds Fb.07,the inverter will stop
reducing its output frequency.When DC bus voltage become lower than Fb.07,the
deceleration continues.as shown in following figure:
Code
Fb.09
Fb.10
Fb.09:
0:Disabled
1:Enabled
Fb.10:The automatic level of current limiting the factory values related to the
model,among: G-type:160%;P-type:120%
When inverter is running in large load,the actual rate of climb motor speed will less
than output frequency rate of climb.If measures are not taken,it will lead to accelerated
flow of failure and cause the inverter tripping.
