12.6 Variables of the motor control (oscilloscope signals)
The system variables of the internal motor control listed in the following table can be recorded with
the oscilloscope for diagnostic and documentation purposes.
Tip!
The exact position of a variable in the motor control can be obtained from the
corresponding signal flow.
Note!
In comparison to all other variable values, the system variables of the internal motor
control have a cycle offset of 2 ... 3 ms!
Variable of the motor control Meaning
Signal flow - servo control for synchronous motor ( 159)
Signal flow - servo control for asynchronous motor
