Multiple servo amplifiers interconnected via the intermediate circuit

(DC+, DC-)
– Multiple servo amplifiers of the same series with mains voltage
from the same mains can be operated on a common intermediate
circuit.
– 90% o f t he total output of all the servo amplifiers is always availa-
ble for peak and continuous output. In the case of overvoltage, the
amplifier shuts down at the lowest shutdown threshold based on
the tolerance (as described above for the single amplifier).
The technical details for the brake resistor depend on the type of ser-

vo amplifier and the mains voltage.
Multiple servo amplifiers can be interconnected via the direct current in-
termediate circuit ("intermediate circuit" for short). This interconnection
is termed a multi axis system.
This connection:
Balances the braking and operating energy of multiple axes.

Distributes the braking energy over multiple brake resistors.

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 amplifiers with higher outputs.
- Ensure that the total rated currents of all the servo amplifiers
connected in parallel in an intermediate circuit is not exceeded.
