Speed control loop measurement
Functionality
The response characteristics for the motor measuring system are analyzed when measuring
the speed control loop. Various measurement parameter lists are available depending on the
basic measurement setting which has been selected.
Operating path
Operating path for measuring the speed control loop: Operating area switchover >
"Commissioning" > "Optimization/Test" > "Speed control loop"
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.
IBN CNC: NCK, PLC, drive
