Meaning
You can select the HW enable with
the "Function DI" parameter and
select the input delay with the "Input
delay" parameter.
The signal of the DIn.0 digital input
is interpreted by the TM Pulse
2x24V, after filtering by the input
delay, as the start of the output
sequence.
Pulses are output at the DQn.A
digital output for the set pulse dura-
tion.
Indicates the signal level at the DQn.B digital output.
0 at the DQn.B digital output
1 at the DQn.B digital output
Indicates the signal level at the DIn.0 digital input.
Signal 0 at the DIn.0 digital input
Signal 1 at the DIn.0 digital input
2 Ampere output: Full scale value 27,648, means 2,000 mA
4 Ampere output: Full scale value 27,648, means 4,000 mA
32,767 means no valid current measurement available; for example, during
the very first period
Value range
0 = HW enable cleared
1 = HW enable issued
0 → 1 = Start of the output
sequence; dependent on the
software enable
(SW_ENABLE)
0 = no pulse
1 = pulse
