15 Parameter change-over
For up to 32 freely selectable parameters, this basic function provides a change-over between four
sets with different parameter values.
The parameter list is created in the same way as the user menu is composed, namely by means of
parameterisation. In the »Engineer«, a user-friendly parameterisation dialog with import and
export functions is available for this purpose.
Motor data changeover
From version 12.00.00 , an optional changeover between four parameter sets with different motor
and control settings is supported in addition.
The optional motor data changeover is provided for applications/machines which have multiple
axes controlled successively but which do not require the simultaneous operation of multiple
motors. In this case, the very same controller can control the motors successively. Advantages of this
solution: Fewer components (controllers) and hence less energy consumption.
[15-1] Principle of the selective control of multiple motors using one controller
 Motor data changeover
 Motor changeover (e.g. via motor contactors)
Principle:
• The motor which is being controlled at
the moment is connected to the
controller via motor contactors. (The
contactor system can e.g. be controlled
via the digital outputs of the
controller.)
• At the same time, the motor data
changeover serves to activate the
motor and control settings suitable for
the motor in the controller.
Note:
The motor data changeover is carried out
within 2 ms and hence within the opening
and closing times of most motor
contactors.
