Measuring functions
The following measurement functions are available for measuring the speed control loop:
Measuring type
Reference frequency response
(downstream of the speed setpoint filter)
Reference frequency response (upstream
of the speed setpoint filter)
Setpoint step change (downstream of the
speed setpoint filter)
Interference frequency response (fault
downstream of the current setpoint filter)
Disturbance variable step change (fault
downstream of the current setpoint filter)
Speed-controlled system (excitation
downstream of the current setpoint filter)
Frequency response of the mechanical
parts
1) The machine axis in question must have both a direct and an indirect measuring system to
determine the frequency response of the mechanical parts.
Measurement
The measurement sequence is divided into the following steps:
1. Setting the traverse range monitoring and the enable logic
2. Selecting the measuring type and measured variable
3. Setting the parameters, softkey "Measuring parameters"
4. Displaying the measurement results, softkey "Display"
The reference frequency response measurement determines the transmission ratio of the
speed controller.
