Selecting the setpoints
Operating mode/Setpoint selectors
In the operating modes
Torque control
and
Speed control
, the setpoint source can be
selected.
Figure 27: "Setpoint selectors" windows - "Speed control" tab
The following setpoint sources can be selected:
l
Analog input
l
Fixed value 1 (this is also used by fieldbus systems and can be labelled
accordingly: CANopen/EtherCAT/PROFINET, etc.) (the setting depends on the
enable logic)
l
Fixed value 2 (the setting depends on the enable logic)
l
Fixed value 3 (the setting depends on the enable logic)
l
Synchronous speed
l
Master frequency input as PWM input
If no setpoint source is activated, the setpoint is zero.
Two additional selectors (
Selector B
and
Selector C
) can be used to select additional
sources as setpoints and/or limit values. These will not be fed through the ramp generator,
however. The total setpoint is the sum of all of the values. The ramp can be parameterised
as the acceleration or deceleration time depending on the direction.
In addition, the torque limitation can be activated in the
Setpoint selectors
menu for the
speed setpoint selection. It can be asymmetric or symmetric and the limitation source can
be selected as desired. In the example above,
Fixed value 1
has been selected as the
source for a symmetric torque limitation.
