3.6 Setting the Configuration
Figure 59
With the block configured to Mode = Fixed, the block produces a constant current
on the terminal outputs, regardless of the value on the Signal input. The constant
current is defined by the parameter FixedCurrent. This feature is useful when
powering feedback potentiometers with current when using Three State Pulse
outputs with feedback. The FixedCurrent parameter setting overrides the settings
of MinCurrent and MaxCurrent.
If the output is configured as a Current output the current range can be defined by
setting the parameters MinCurrent and MaxCurrent.
The input Signal is in the range 0–100%. In Direct mode MinCurrent corresponds
to 0%, MaxCurrent to 100%. In Reverse mode MinCurrent corresponds to 100%,
MaxCurrent to 0%.
For more information concerning the Alarm parameter and related functions
please refer to Appendix B Error, Warning and Information Messages.
The Loop parameter applies only to the ECA600 and is used to define the control
loop used.
