DBU Voltage Jumper Settings
The power source for the
DURa
pUlse
dynamic braking unit is DC bus voltage from the +(P)
and -(N) terminals of the GS drive. It is important to set the voltage selection jumper of the
DURa
pUlse
dynamic braking unit accurately based on the input power of the GS drive before
operation. The voltage selection jumper setting determines the GS DC bus voltage level at
which dynamic braking is applied.

For DURApulse AC drives, set the “Over Voltage Stall Prevention” parameter as “close (1)”
to disable over-voltage stall prevention (P6.05 in GS3; P6.11 in GS4). This will ensure a
stable deceleration characteristic.
