As an alternative to limiting the output values by a fixed value, linking to an analog input value is also
possible. The analog value is limited via parameters
519, but does not consider the
Reference Percentage
ence percentage value channel.
The assignment is done with the help of the parameters
Isq Limit Source Generator Op.
The sources for the torque limits can be selected via the parameters
736 and
Torque Limit Source Gen. Op.

The limit values and assignment to different limit value sources are data set related in
the configurations. The use of the data record changeover demands an examination of
the parameters in question.
7.9.5.3.3 Switching over between speed control and torque control
Via the signal assigned to parameter
control and torque control. See chapter 7.6.6.10 "n-/T-control changeover".

Acceleration pre-control

725 Operation Mode
The acceleration pre-control controlled parallel to the speed controller reduces the reaction time of the
drive system to a change of reference values.
The acceleration pre-control is active in the speed-controlled configurations and can be activated via

737.
Multifunction input 1 is the source. Via parameter
452, multifunction input 1 must be set up as a voltage or
MFI1
current input.
Multifunction input 2 is the source. Via parameter
562, multifunction input 2 must be set up as a voltage or
MFI2
current input.
The percentage signal at the repetition frequency input (IN2D, ter-
minal X11.5).
Operation Mode IN2D
