Current measurement
Current measurement is available in Pulse train mode. Your control program can use current
measurement for control and diagnostic purposes.
For more information, refer to Function: Current measurement (Page 76).

Meaning
2 = Set the "Pulse train" operating
mode.
The output supports higher fre-
quencies (see pulse duration
range).
You can use the DIn.0 digital input
as an input or as a hardware ena-
ble. The signal at DIn.0 is interpret-
ed by the TM Pulse 2x24V, after
noise filtering by the input delay, as
the start of the output sequence.
Defines the format of the duty cycle
ratio value.
DIn.0 digital input must be stable
over the delay time (signal noise
suppression).
Period duration of the output se-
quence: You can change the period
duration in your control program
using the control interface field
SLOT.
