Properties of the fault buffer:

A new fault incident encompasses one or more faults and is entered in fault incident 1.

The entries are arranged in the buffer according to their time of occurrence.

If a new fault incident occurs, the fault buffer is reorganized. This history is recorded in fault

incidents 2 to 8.

If the cause of at least one fault in fault incident 1 is remedied and acknowledged, the fault buffer

is reorganized. The faults which have not been remedied remain in fault incident 1.

When 8 faults have been entered in fault incident 1 and a new fault occurs, the fault in theparameters in index 7 is overwritten by the new fault.

r0944 is incremented each time the fault buffer changes.

A fault value (r0949) can be output for a fault. The fault value is used to diagnose the fault

accurately; please refer to the fault description for details of the meaning.

Clearing the fault buffer: POWER ON clears the entire buffer.

The fault buffer is reset as follows: p0952 = 0.

Diagnostic with warning buffer

Properties of the warning buffer:

The entries are arranged in the buffer according to their

time of occurrence.

When 8 warnings have been entered in the warning buffer

and a new warning occurs, the warning in the parameters

in index 7 is overwritten by the new warning.

r2121 is incremented each time the warning bufferchanges.

A warning value (r2124) can be output for a warning. Thewarning value is used to diagnose the warning accurately;

please refer to the warning description for details of the

meaning.

buffer.

Function generator

Operating modes of the function generator:

1. Connector output2. Current setpoint downstream of filter (current setpoint filter)

3. Disturbing torque (downstream of current setpoint filter)

4. Speed setpoint downstream of filter (speed setpoint filter)

5. Current setpoint upstream of filter (current setpoint filter)

6. Speed setpoint upstream of filter (speed setpoint filter)

parameterizable signal shapes

-- Square--wave

-- Staircase

-- Triangular

-- PRBS (pseudo random binary

signal, white noise)

-- Sinusoidal

The function generator can be used to

generate different signal shapes. Depending on the mode setting, this setpointcan then be fed into the control system, forexample as a current setpoint, disturbingtorque or speed setpoint.

The impact of superimposed control loops isautomatically suppressed.
