System Program

The System Program, as described in Section 5.4, is developed for each drive application to
configure the VFD to function as desired by the end user. The System Program allows the
end user to define the drive operation, where possible, so that system response and I/O
configuration is configured for the application. The system program is used to define
reference sources, select a subset of operating parameters, configure all I/O, and to define
alarms/fault conditions as desired by the end user.
Note
Internal drive-generated faults defined for drive protection cannot be modified by the SOP.
The System Program is downloaded onto the NXG drive in non-volatile memory, and can be
field-modified for changing requirements. Note that the drive must be in an idle state (i.e.,
output disabled) for a new SOP to be utilized.
