Measurement of current control loop
Functionality
The current control loop only needs to be measured for diagnostic purposes if there is a fault
or if no standard data was used for the motor/power module combination, and which resulted
in unsatisfactory speed controller frequency responses.
CAUTION
The user must take special safety measures when measuring the current control loop (e.g.
secure drive clamping) for hanging axes without external counterweight.
Operating path
Operating path for measuring the current control loop: Operating area switchover >
Commissioning > Optimization/Test > Current control loop
Measuring functions
The following measuring functions are available for measuring the current control loop:
Measuring type
Reference frequency response
(downstream of the current setpoint filter)
Setpoint step change (downstream of the
current setpoint filter)
Measurement
The measurement sequence is divided into the following steps:
1. Setting the traverse range monitoring and the enable logic
2. Selecting the measurement type
3. Setting the parameters, softkey "Measuring parameters"
4. Displaying the measurement results, softkey "Display"
