Motion Control Override
The Motion Control Override Function can be used to transmit the motion profile via
serial communication (VABus or Modbus). Therefore in the User software VPlus for
Windows a motion profile can be used when a control is not finished programming
during commissioning. This function can also be used as a simulation mode.
The Function Motion Control Override do not support the following modes:
•
Interpolated Mode.
•
Cyclic Synchronous Position Mode
•
Cyclic Synchronous Velocity Mode

results, that the value of the Motion Control Interface links of
Parameters 1292…1297 are used. Settings deviating from the factory setting will re-
sult in the usage of the individual parameter. It is possible to set certain aspects of the
trajectory via the Override function and other values via the Motion Control Interface.
The target position “-1 u” cannot be used as target position, because 1455
