Pr.25 Over-voltage Stall Prevention

Factory Setting d01
Units None
Settings d00 Disable over-voltage stall prevention
d01 Enbable over-voltage stall prevention
During deceleration, the DC bus voltage may exceed the maximum amount allowable
due to motor regeneration. When this function is enabled, the AC drive will cease to
decelerate and then maintain a constant output frequency. The drive will only resume
deceleration when the voltage drops below the preset value.
