P1210

The maximum value depends on the b maXX

used, up to 410.0 V for single-phase de-

vices and up to 820.0 V for three-phase devices.

During deceleration, the DC bus voltage may exceed its maximum allowable value due

to motor regeneration. When this function is enabled, the b maXX

1000 will not deceler-

ate further and keep the output frequency constant until the voltage drops below the pre-

set value again.

Over-voltage stall prevention must be disabled (ZP1210– = 0) when a brake unit or brake

resistor is used.

STOP BM_u_OverVoltageStallPrevention 10:1

NOTE

With moderate inertia load, over-voltage stall prevention will not occur and the real decelera-

tion time will be equal to the setting of deceleration time. The b maXX

1000 will automatically

extend the deceleration time with high inertia loads. If the deceleration time is critical for the

application, a brake resistor or brake unit should be used.
