Behaviour after an overvoltage in the DC bus dependent on code C0913
Which products are affected?
9300vector 110…400 kW SW7.1
Function description:
After an OU message and enabling of the pulses the output voltage of the drive controller is increased slowly along a linear ramp. The steepness of the voltage ramp (default setting: 0.488 V/ms) limits the current increase after a pulse enable. If the voltage ramp finally exceeds the actual frequency-dependent output voltage the linear limitation is set to the upper range value (1000 V) and thus deactivated.
Thanks to code C0913 is now possible to reduce the increase in the voltage ramp by factor 2.
Code C0913 Value '0': The increase in the voltage ramp reduced by factor 2 is deactivated (default setting).
Code C0913 Value '1': The increase in the voltage ramp reduced by factor 2 is activated.
According to the Lenze default setting code C0913 is set to '0'.
