Technical data of product parameters

Leakage current via the PE conductor results from the combination of equipment and
cable leakage currents. The leakage current frequency pattern comprises a number of
frequencies, whereby the residual-current circuit breakers definitively evaluate the 50Hz
current. As a rule of thumb, the following assumption can be made for leakage current on
our low-capacity cables at a mains voltage of 400 V, depending on the clock frequency of
the output stage:
Ileak = n x 20mA + L x 1mA/m at 8kHz clock frequency at the DSTD190 3BSE004723R1frequency at the output stage
(where Ileak=leakage current, n=number of amplifiers, L=length of motor cable)
At other mains voltage ratings, the leakage current varies in proportion to the voltage.
Example: 2 x servo amplifiers + a 25m motor cable at a clock DSTD 190leakage current.
Since the leakage current to PE is more than 3.5 mA, in compliance with
IEC 61800-5-1 the PE connection must either be doubled or a DSTD 190 ​must be used. Use the PE terminal X0/3 and the PE bolt in order
to fulfil this requirement.
The following measures can be used to minimise leakage currents.
— Reduce the length of the engine cable
— Use low-capacity cables (see p.45)
— Remove external EMC filters (radio-interference suppressors are integrated)
6.9.2 Residual-current circuit breakers (FI)
In conformity with IEC 60364-4-41 – Regulations for installation and IEC 60204 – Electrical equipment of machinery, residual-current circuit-breakers (called FI below) can be
used provided the requisite regulations are complied with. The SERVOSTAR 400 is a
3-phase system with a B6 bridge. Therefore, FIs which are sensitive to all currents
must be used in order to detect any D.C. fault currente.
