Pulse width
Pulse width (t):
The pulse width limit can be set
between 2…500
ms
(example: 20 ms).
The actual pulse width is dynamically adjusted based on the
current flow, but at least the set value.
The duty cycle is min. 50 %. The off cycle can be bigger
Signal behavior:
The signal is defined as: t = ON and (Period
–
t) = OFF:
Parameters that can be set:
Pulse width (t): 2 - 500 ms
Pulse value (UPP): 0.001 - 1000 units per pulse
