Table 7.1 Recommended mains fuses from the manufacturer SIBA (www.siba-

• Motor protection switch
− Size 1 to Size 5
The motor protection switch should always be installed additional to
the mains fuses. It serves as an overload protector for the device, mains
choke and mains filter in the range up to the permissible overload. The
rated current of the motor protection switch (“Power switch for system
and motor protection”, trip class 10, SIEMENS series SIRIUS 3RV10 or
SIRIUS 3RV20) should be selected according to the lowest rated current
I
rated (f_sw and U_mains)
of the components used (mains choke, mains filter,
AC-AC servo drive).
− Size 6 to Size 7
The motor protection switch is not required if, instead of mains fuses of
utilisation class gG, semiconductor fuses of utilisation class gRL (gS) are
used (see table 7.1).
• Braking resistor
The braking resistor of the AC-AC servo drive should be dimensioned such
that the total regenerative power of the multi-axis system can be dissi-
pated. When dimensioning the connecting cables of the braking resistor,
ensure that the mains-side protective devices are safely tripped in the event
of a fault. Note that the ratio of the currents I
DC bus eff
/ I
mains side eff
= √(3/2) .
