You can measure both digital and analog drives. However, the bandwidth avail-
able for measuring is limited by the position controller or PROFIBUS cycles.
You will find detailed information about frequency measurement and optimiza-
tion of the torque/current and speed control loop of the SIMODRIVE 611 univer-
sal/E, POSMO CD/CA and SI drives in the online help of the start-up tool Simo-

A measurement of the torque control loop with HMI Advanced is not possible
within the framework of SINUMERIK 840Di.

This measurement function basically analyses the response to the motor mea-
suring system. Depending on which basic measurement setting has been se-
lected, various measurement parameters lists as described below are made
The traversing range monitoring function is set and the enabling logic (external/
internal) selected in the speed control loop measurement main screen.

Four different types of measurement are available for testing the speed con-
– Reference frequency response
– Setpoint step change
– Interference frequency response
– Disturbance step change
– Speed controller system
