5.3.8 I/O Con󹪝guration
The control system contains a programmable software feature that allows for interaction with
the functionality of the drive, this is called the system operating program (SOP) interpreter.
The SOP interpreter is built into the drive core software for execution of the SOP. To con󹪝gure the
I/O, both internal and external, the IO must be assigned within the SOP for the system.
The SOP interpreter maps the digital I/O points in the hardware to internal drive system 󹪞ags
based on the information in the SOP. It is also possible for inputs and outputs not speci󹪝cally
assigned to be inferred in the SOP by use of their dedicated function in a program statement.
In the more advanced format, simple Boolean relationships allow more complex combinations
of external or internal inputs. In addition, timers, counters, and comparators, allow great
con󹪝gurability to the logic.
Note
The SOP is written and compiled externally, therefore error checking is done at the compiler level.
Follow correct implementation of the SOP as described in Chapter Operating the Software.
If not followed correctly this could result in drive instability.
5.3.9 Dedicated I/O
NXGPro+ control systems must utilize at least one user I/O board. Some of the I/O on the 󹪝rst
board have been given standard assignments. This improves response time, and prevents
changes in the SOP from a󹪜ecting the drive protection measures assigned to the speci󹪝c I/O.
These standard assignments are referred to as dedicated I/O. The following sections describe
these dedicated assignments.
5.3.10 Dedicated I/O for Type 4 Pre-charge
The following are Type 4 pre-charge assignments. They are internally controlled and do not
require SOP intervention.
Note
This feature will be released in a later sofware version.
