D
: Duration of measured value output
The duration of measured value output (t
D
) depends on
• The selected baud rate (BR),
• The number of axes (M)
• The number of blank lines (L)

Operating parameters for measured value output
The following operating parameters will influence measured
value output — regardless of how you start it.
Number of blank lines after each measured value: P51
Number of blank lines after measured value: P51 = 0 to 99
You can also use the signal for measured value output to
influence position display.
Screen display during measured value output: P23
The display is not stopped during measured
value output (Off):
P23 = 0
The display is stopped during measured value output
and remains stopped as long as the switching input
“output measured value” is active (Concrnt):
P23 = 1
The display is stopped but is updated by every
measured value output (Frozen):
P23 = 2
