Constant pulse length:
Figure 18: Position Distance" Trigger Mode, constant trigger pulse length
The Pos. Distance Trig. High Time Definition parameter has the value 1.
The trigger pulse length is constant. The trigger high time is adjustable using the Position Distance
Trigger High Time parameter (ID 0x18000401). The parameter value is given in seconds. If the
parameter value is set to 0 (default setting), the length of a trigger pulse is one servo cycle (50 µs).
Possible values for the Position Distance Trigger High Time parameter (ID 0x18000401) depend on
the axis velocity and the TriggerStep value. Pulses can get lost if the pulse length and/or
TriggerStep values are not suitable for the current axis velocity, see figure below for an example.
