Multi-axis systems
With multi-axis systems please note the specific conditions of your plant. On multi-axis sys-
tems, servo amplifiers can be interconnected via the intermediate circuit.
As with single-axis systems, max. cable runs can only be achieved if the material require-
ments are strictly observed.
NOTICE
High transient currents between connected intermediate circuits can destroy
the servo amplifier.
- Supply the servo amplifier from the same mains (identical mains voltage).
- Do not wire servo amplifiers with smaller outputs between two servo ampli-
fiers with higher outputs.
- Ensure that the total rated currents of all the servo amplifiers connected in
parallel in an intermediate circuit does not exceed 96A
RMS
(140 A
PEAK
).

Energy store
Dimensions (HxWxD): 300 x 100 x 201 mm
The energy stores are connected to the direct current intermediate circuit and they store the
energy that the motor produces in the generating operation. This energy is usually imple-
mented via brake resistors in power dissipation.
If the energy is required, for example, with the next acceleration cycle, the energy stores
supply the saved energy back in the intermediate circuit.
