3.3 Brake chopper<br />
The power output stage comprises a brake chopper with a braking resistor. If the admissible charging<br />
capacity of the DC-link is exceeded during regenerative power supply, the internal braking resistor can<br />
convert the braking energy into heat. The brake chopper is controlled by the software. The internal<br />
braking resistor is overload-protected by the firmware.<br />
If in a special application the capacity of the internal braking resistor is not sufficient, the resistor can<br />
be switched off by removing the jumper between pins BR-CH and BR-INT of connector [X9]. Instead,<br />
an external braking resistor has to be connected between pins BR-CH and BR-EXT. The values of this<br />
braking resistor must not be below certain predefined minimum values (see Table 11, page 34). The<br />
output is protected against a short-circuit in the braking resistor or in its feed line.<br />
Pin BR-CH is connected to the positive DC-link potential and therefore not protected<br />
against ground fault or shorts to mains power or negative DC-link voltage.<br />
Internal and external braking resistors cannot be used simultaneously. External braking resistors are<br />
not automatically overload-protected by the device.<br />
3.4 Communication interfaces<br />
The <strong>ARS</strong> 2300 servo positioning controller has several communication interfaces. The servo<br />
positioning controller is equipped with a RS232 interface being of prime importance for the connection<br />
of a PC and use of the ServoCommander parameterization tool.<br />
In addition, the basic unit of the <strong>ARS</strong> 2300 servo positioning controller is equipped with a CANopen<br />
interface.<br />
PROFIBUS-DP can be used as an extension option using plug-in modules. Other field bus modules<br />
are under preparation. If required, it is also possible to implement customized field bus protocols.<br />
With this product configuration, the servo positioning controllers always acts as a slave on the field<br />
bus.<br />
3.4.1 RS232 interface<br />
The RS232 protocol is mainly intended as a parameterization interface. However, it can also be used<br />
to control the <strong>ARS</strong> 2300 servo positioning controller.<br />
