Bleeder monitor features of the RAC 2.2
Activated bleeder monitoring prevents a device with overheated bleeder
from being switched on again. The display then shows „BLEEDER“.
Activated bleeder monitoring also signals „BLEEDER“, if the RAC 2.2
has been inadvertently installed with a bleeder!
Bleeder monitor features of the RAC 3.1
Bleeder montioring is always operative when a bleeder is fitted. A
missing bleeder is therefore not diagnosed!
During a mains failure, in both control units RAC 2.2 and 3.1 (with
additional bleeder option), the decision to brake the drive immediately or
whether the internal ramp or the NC controller specifies the speed
command value for deceleration, can be made with the PQ FUNCT value
in the switchable parameter records. The tool and workpiece can thus be
separated without damage during NC braking.

3.20 Performance during mains failure and E-stop
(KDA, TDA)
Apart from the main drive with KDA or TDA, servo drives can also be
connected in the modular drive system to the same power supply
module.
Modular drive system requirements:
• Stopping the servo drives has priority over stopping the main drive.
• The total power regenerated by the drives during braking must not
exceed the regenerated power of the supply unit, otherwise the voltage
in the DC bus circuit rises to inadmissible levels.
• If the DC bus voltage, as a result of the power that is regenerated when
the drives are braking, reaches the permissible limit value, then the
KDA/TDA interrupts the braking of the main spindle drives. If the voltage
drops, then the main spindle drives return to braking mode.
The command value is switched to zero either abruptly or with the use of
ramps, depending upon the parameter FUNCT2 (A06).
If the control unit must separate tool and workpiece by switching the
command value to zero, then an NCB jumper must be installed on the
supply module (KDV, TVD or KVR, etc). All drives connected to the
supply module must, in this case, be braked by the control unit via the
speed command value!
