FUNCTION
:
Cam table master interval and phase shift
DESCRIPTION:
The EP command defines the ECAM table master interval and phase shift. The interval m is
the difference in master position between table entries. The phase shift n instantaneously
moves the graph of slave position versus master position left (negative) or right (positive)
and is used to make on-the-fly corrections to the slaves. Up to 257 points may be
specified.
ARGUMENTS
: EP m,n
where
m is the master interval and is a positive integer in the range between 1 and 32,767 master
counts. m cannot be changed while ECAM is running.
m = ? Returns the value of the interval, m.
n is the phase shift and is an integer between -2,147,483,648 and 2,147,483,647 master
counts. n can be changed while ECAM is running.
