MOD 30ML APPLICATION
GENERAL
Figure 3 shows a block diagram of the output holder compound strategy. This strategy
contains the PID, display and I/O for one loop. When using this compound you will be
required to complete a few strategy changes to make it fit your application. These
changes are outlined in Loading the Compound.
The purpose of the output holder compound is to cause the control loop output to
synchronize its output to that of the output holder before turning its field output on. This
will in turn cause a bumpless transfer. This happens only when the controller first
initializes at power up.
