Axis is moving continuously in positive direction
Illustration 2.122 Example 1 - Behavior of Output in Positive
Direction
Illustration 2.122 shows the behavior of the output when
the axis is moving continuously in a positive direction. The
axis is a modulo axis with a modulo length of 5000. It does
not include on/off compensation or hysteresis.

Resulting position depends on the current velocity
Illustration 2.123 Example 1 - Use of On/Off Compensation
Illustration 2.123 shows the additional use of on compen-
sation of 125 ms and off compensation of 250 ms. The axis
is moving continuously in a positive direction.

Axis is moving continously in negative direction
Illustration 2.124 Example 1 - Behavior of Output in Negative
Direction
Illustration 2.124 shows the behavior of the output when
the axis is moving continuously in a negative direction.
The axis is a modulo axis with a modulo length of 5000. It
does not include on/off compensation or hysteresis.

2.5.2 ISD Touch Probe
This functionality stores the position actual value and a
time stamp at the rising or falling edge of the configured
digital input. This functionality is available in all modes of
operation for each input individually.
The function is configured using object 0x60B8 (see
chapter 7.18.1 Parameter: Touch Probe Function (0x60B8)),
where the different options regarding the trigger event
can be selected.
