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 the

parameters 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 buffer changes.

• A warning value (r2124) can be output for a warning. The warning value is used to diagnose the warning accurately; please refer to the warning description for details of the meaning.

• Clearing the warning buffer: POWER ON clears the entire buffer.

• The warning buffer is reset as follows: p2111 = 0

Function generatorOperating 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, for example as a current setpoint, disturbing torque or speed setpoint.

• The impact of superimposed control loops is automatically suppressed.

Trace Functions

The trace function can be used to record measured values over a defined period depending on trigger conditions.

Trigger signals

Measuring functions• Current controller setpoint change (behind the current setpoint filter)• Current controller reference frequency response (behind the current setpoint filter)• Speed controller setpoint change (behind the speed setpoint filter)• Speed controller disturbance step change (fault behind the current setpoint filter)• Speed controller reference frequency response (behind the speed setpoint filter)• Speed controller reference frequency response (upstream of the speed setpoint filter)• Speed controller interference frequency response (fault behind the current setpoint

filter)• Speed-controlled system (excitation downstream of current setpoint filter)
