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 DSQC102 YB161103depending on the clock frequency of
the output stage:
Ileak = n x 20mA + L x 1mA/m at 8kHz clock frequency at the output stage
Ileak = n x 20mA + L x 2mA/m at a 16kHz clock frequency 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 frequency of 8kHz:
2 x 20mA + 25m x 1mA/m = 65mA leakage 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 connecting cable with a cross-section
>10mm² must be used. Use the PE terminals and the PE bolt in order to fulfil this
requirement.
The following measures can be used to minimize leakage currents.
— Reduce the length of the engine cable
— Use low-capacity cables (see p.57)
— Remove external EMC filters (radio-interference suppressors are integrated)
5.10.2 Residual current protective device DSQC102 YB161103
In conformity withDSQC102 YB161103 Regulations for installation and IEC 60204 – Electrical equipment of machinery, residual current protective devices (called DSQC102 YB161103below) can
be used provided the requisite regulations are complied with. The S700 is a 3-phase system with a B6 bridge. Therefore, RCDs which are sensitive to all currents must be
used in order to detect any D.C. fault current. Refer to chapter 5.10.1 for the rule of thumb
for determining the leakage current.
Rated residual currents in the DSQC102 YB161103
10 – 30 mA Protection against “indirect contact” for stationary and mobile equipment,
as well as for “direct contact”.
50 – 300 mA Protection against “indirect contact” for stationary equipment
Recommendation: In order to protect against direct contact (with motor cables shorter
than 5 m) we recommend that each servo amplifier be protected individually using a
30mA RCD which is sensitive to all currents.
If you use a selective RCD, the more intelligent evaluation process will prevent spurious
tripping of the RCD.DSQC102 YB161103DSQC102 YB161103DSQC102 YB161103DSQC102 YB161103
