9.3.1.1.3. ASSEMBLY INSTANCE 23 – EXTENDED SPEED AND TORQUE CONTROL OUTPUT
Control and Status Word monitoring values
When using this telegram, monitoring values contains values as shown in the following table. Status
word values depend on used input instance.
9.3.1.1.4. ASSEMBLY INSTANCE 25 – EXTENDED PROCESS CONTROL OUTPUT
The extended process control assembly can be used to send process reference value directly to the
application. The Process Reference value destination can be selected with the Drive Mode byte
according to the following table. This should be configured in the application as the receiving input.
To the other direction (input assembly instance 75), the ProcessDataOut1 is always mapped to the
Process Actual. Note that the process reference value is sent to the drive only when NetProc bit is
set.
The VACON
®
AC drives do not support the actual “Process Control”-mode. Therefore the Drive Mode
cannot be set to the Process Control by using the AC/DC Drive Object attribute, and the Drive Mode
parameter in this assembly is only used to select the process reference. With these mappings, the
Process Reference and Process Actual can be used with an application that supports the PID
control.
