7.3 Linking transient registers together

The 'Link to:' field will accept any register number from 0 through 15. If a
Link is set to a register which Trans.Type field is 'Empty', an error message
will appear when the transient register contents is downloaded. The following
transient program, will result in the error message shown below:
The error is shown to be in register 1 where a Link is made to register 2.
Register 2 however is set to empty so its contents will not be set by
downloading the transient register information.
To erase a Link field, enter a negative value as a link destination. For
example, entering -1 will cause the field to be reset. Empty Link fields
indicate no link is made to another register.
WARNING: Linking registers will cause a slight delay when switching from
one transient register to the next. This delay is approximately 3 msec when
the "Link to" register contains a single parameter transient or 4 msec when
the "Link to" register contains a "VFSweep" transient. This delay will make it
difficult to maintain successive phase angle relationships between register
steps.
WARNING: If the "Start ø" field is used, a substantial delay of up to one
signal period may occur as the controller needs to wait for the 0° point first in
order to determine the start of the next transient. If this field is left blank, the
transient will be executed immediately after the 3 to 4 msec delay.
