Description

The dv/dt filter plus VPL (Voltage Peak Limiter) consists of two components: the dv/dt
reactor and the voltage limiting network (Voltage Peak Limiter), which limits voltage peaks
and returns the energy to the DC link.
The dv/dt filter plus VPL is to be used for motors for which the voltage strength 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 VPL limits the rate of voltage rise to values < 500 V/µs and the typical
voltage peaks at rated line voltages to the values below (with motor cable lengths < 150 m):
< 1000 V at V
Components
The Order Nos. of the individual components (dv/dt reactor and voltage limiting network) are
listed in the following table:

Safety information

Caution
The cooling clearances of 100 mm above and below the components must be observed.
Note
The connecting cables to the Motor Module must be kept as short as possible (max. 5 m).
