14.4.3 Position control measurement
Functionality
This measuring function basically analyzes the response to the active position measuring
system. If the function is activated for a spindle without a position measuring system, an
alarm is displayed. Depending on the measured variable selected, various measurement
parameter lists are displayed.

Measuring functions
The following measuring functions are available for measuring the position control loop:
Measuring type Measured variable
Reference frequency response Actual position/position setpoint
Setpoint step change Measured variable 1: Position setpoint
Measured variable 2:
• Actual position value
• System deviation
• Following error
• Speed actual value
Setpoint ramp Measured variable 1: Position setpoint
Measured variable 2:
• Actual position value
• System deviation
• Following error
• Speed actual value
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"
