3.6.8.3 Connection of the power voltage of 2 C3H 3AC
devices
In order to improve the conditions during brake operation, the DC power voltage of
2 servo axes may be connected.
The capacity as well as the storable energy are increased; furthermore the braking
energy of one servo axis may be utilized by a second servo axis, depending on the
application.
It is not permitted to connect the power voltage in order to use one brake
circuit for two servo axes, as this function cannot be ensured reliably.
Note the following:
Caution! In case of non-compliance with the following instructions, the
device may be destroyed!
You can only connect two similar servo axes (same power supply; same rated
currents)
Connected servo axes must always be fed separately via the AC power supply.
If the external pre-fuse of one of the servo axes takes action, the second servo
axis must also be disconnected automatically.
Please connect as follows:
Servo axis 1 DC+ with servo axis 2 DC+
Servo axis 1 DC- with servo axis 2 DC-
