Parameter Explanation
1. 2. 3. 4. 5. 6.
CTABSEG INT:
Number
of curve
seg‐
ments
STRING:
Storage
location:
"SRAM",
"DRAM"
STRING:
Segment
type:
"L": Line‐
ar
"P": Poly‐
nomial
Determines the num‐

type
If parameter 2 is not
programmed, the sum
of the linear and poly‐
nomial segments is
output.

"P": Poly‐
nomial
Determines the num‐
ber of still possible
curve segments of the
specified segment
type in the specified
memory
