Armature infeed when fuse tripped without operation enable: See also our Safety Integrated Manual available on the Internet. The gate pulses are formed on the CUD1, the gate pulse transformers are located on the power interface module.

You can check whether it is enabled in parameter n Check r Check output voltage with voltmeter. Replacement of the CUD1: The fault is acknowledged via bit 7 of the control word and pressing the P key on the PMU: Line undervoltage or armature voltage too high.

Motor operation on the converter, speed n and torque M: The base point of the load resistors is then at frame potential, this can be 6rq27 by resistance measurement using an ohmmeter in order to avoid a short circuit of the load voltage when measuring with a grounded oscilloscope.

Setting the ramp-function generator to the content of the connector number in P PTC mannual Warning, or switch off, no temperature display possible. In this case, read out the following parameters: One valve must always be conducting in two phases for each to permit current flow in the DC circuit.

Mahual structure of the 6RA70 The structure of the controller for the armature circuit: The friction is speed dependent, the torque required to overcome the friction is derived and added to the speed controller output. A precontrol is active at the same time and has a different characteristic curve than the armature current control loop because it includes a half-controlled bridge circuit. Check current controller optimization, perform current controller optimization run.

Proceed in the same way for the BDS parameters. Monitoring and protecting circuits for motor and machine tool amnual included.

If all checks are OK but still operating status o4. The transformer apparent power is: The following values can provide some orientation help: The current transformer load for each current transformer is on the manula interface module and is 10 ohm. By solving this algebraic 61 equation and re-transformation to the original, this solution can be calculated as a differential equation.

For DC link voltage up to approx. Test with connected thyristor: Motor field as load must be connected. NUM Operator Panel and Please also remember that dangerous voltages are also present on the power interface and field module.

These parameters must be adjusted manually after the download. If, among multiple small lag elements in the controlled system, there is one that has a greater time constant e.

For further information see the description for U in the Operating Instructions. The rated motor voltage is reached when manul rated speed is at nominal flux. Optimization of the PI controller according to the absolute value optimum The absolute value optimum is used if there is no integral-action element in the controlled system. One advantage here is that the controlled system gain of the speed control loop is adapted suitably automatically within the field weakening range of the motor, producing a stable speed control response.

FAQ for 6RA70 DC MASTER and SIMOREG CM

The current converter can be tested without a connected motor with variable voltage. Only when you have completed this basic start-up procedure can you set the parameters 6rx27 other functions such as technological closed-loop control and Profibus. Measurement at thyristor gate: Fault message during the optimization run, see fault value in the fault description.

I look for a PDF Ebook about:. For remedy and alternatives to the above mabual, see the description for F in this description. Total thermal derating factor as a function of the ambient temperature and installation altitude of the device.

For calculation, see below. Rated DC device current for the field acc. With this transfer function it is possible to obtain information about the stability of the system using suitable methods, for example, the root locus method see the relevant literature.

The product is new, it has never been installed or used. It also gives details of the bearing type installed in the motor. The operating status of the device: If the motor was already being operated with a converter and a smoothing reactor is in use, this must be retained when the 6RA70 is retrofitted.

Measurement should be performed when the winding is cooled 20 — 30 degrees room temperature. Manual optimization See Section 7. Constant k2 is dependent on the number of armature windings and the dimensions of the machine.

Alternative special filters for use in IT systems are available on request.
