DC−bus voltage (U

)

( Stop!

This setpoint must be below the operating threshold of a possibly connected

braking unit. If a connected braking unit is activated, the drive will be braked with

the max. possible torque (Imax). The desired operational performance gets lost.

5. Set the setpoint on which the DC bus voltage is to be controlled:

– Set the setpoint to approx. 700 V (C0472/19 = 70 %).
