JetMove 208-480 7.6 External Ballast Resistor and DC Link Connection
Jetter AG 67
Parameters of external ballast resistor in this configuration:
These are the same values as with the internal resistor.
As an alternative, the following parameters can apply to a resistor:
This configuration causes the energy dissipation to be twice as high as it would be if
configured with an internal resistor only.
With both resistors, the internal overload control is working as well as using the
internal ballast resistor only.
Coupling DC Link Circuits of Two or Three
JetMove 208-480
Another way uf utilizing the braking energy of the motor is to couple the DC links of
several JetMove 208-480. In most cases, not all axes of a machine have to brake at
the same time. So, other axes can use the energy coming back for acceleration.
The coupling reduces the heat inside the amplifier emitted by the ballast resistor and
provides a higher dynamic if not all axes accelerate at the same time.
