Measuring machine

The measuring function is used for controller optimization. With measuring function, you can
directly inhibit the influence of higher-level control loops by means of simple
parameterization, and analyze the dynamic response of individual drives.
For easier handling of the controller optimization, predefined measuring functions are
available for selection. The operating mode is automatically set depending on the measuring
function.
● Speed controller setpoint frequency response(before speed setpoint filter)
The speed control loop is closed while all of the higher-level control loops are open. For
the setpoint frequency response on the speed controller, the speed setpoint is activated
by a PRBS signal. The evaluation of the signals is performed in the frequency range.
● Speed control system(excitation after current setpoint filter)
The speed control loop is closed while all of the higher-level control loops are open. For
the measurement of the speed controller system on the speed controller, the speed
setpoint is activated by a PRBS signal. The evaluation of the signals is performed in the
frequency range.

Function description
Seven trigger types are available for your selection:
Immediate recording (default settings)
•
Trigger on rising edge
•
Note:
The digital signals must be set to 1. Otherwise, the rising edge cannot be trig-
gered.
Trigger on falling edge
•
Note:
The digital signals must be set to 0. Otherwise, the falling edge cannot be trig-
gered.
Trigger within the scope
•
Trigger outside of the scope
•
Trigger at alarm
•
Trigger at fault
•
Trigger type settings:
For the last six trigger types, you can select pre-trigger or post-trigger and the
•
trigger signal.
For the fourth and fifth trigger types, you can enter the threshold upper/lower
•
value in the textbox.
