Commissioning
During commissioning, the dV/dt filter compact plus Voltage Peak Limiter must be logged on
using STARTER or the AOP30 operator panel (p0230 = 2).
Note
When the factory settings are restored, parameter p0230 is reset.
The parameter must be reset if the system is commissioned again.

dv/dt filter plus Voltage Peak Limiter (option L10)

Description
The dV/dt filter plus voltage peak limiter comprises two components: the dV/dt reactor and
the Voltage Peak Limiter, which cuts off the voltage peaks and returns the energy to the DC
link.
The dv/dt filters plus Voltage Peak Limiter must be used for motors for which the proof
voltage of the insulation system is unknown or insufficient. Standard motors of the 1LA5,
1LA6 and 1LA8 series only require them at supply voltages > 500 V +10%.
The dv/dt filter plus Voltage Peak Limiter limits the voltage gradient to values < 500 V/µs and
the typical transients to the values below (with motor cable lengths of < 150 m):
● < 1000 V at U
● < 1250 V at 660 V < U
Depending on the converter power, option L10 can be accommodated in the drive converter
cabinet unit or an additional cabinet with a width 400 mm is required.
