Meaning
You can select the interpretation
of the digital input signal on the
output sequence with the "Func-
tion DI" parameter and select the
input delay with the "Input delay"
parameter.
The signal at the DIn.0 digital input
is interpreted by the
TM Pulse 2x24V, after noise
filtering by the input delay, as the
start of the output sequence.
A pulse is output at the DQn.A and
DQn.B digital outputs for the
assigned duty cycle and period
duration.
Meaning
Bit 3 Indicates the signal level at the DIn.0 digital input.
0 0 on DIn.0 digital input
1 1 on DIn.0 digital input
Sequence counter = 0. The sequence counter is not used in PWM mode.
Read as 0
Value range
Function DI = "HW_ENABLE":
0 = HW enable cleared
1 = HW enable issued
0→1 = Start of the output sequence after
the input delay, dependent on the soft-
ware enable (SW_ENABLE)
1→0 = Stop of the output sequence after
the input delay, dependent on the soft-
ware enable (SW_ENABLE).
Function DI = External stop:
0→1 = Stop of the output sequence after
the input delay; dependent on the soft-
ware enable (SW_ENABLE)
No pulse or interpulse period:
DQn.A is 0 V and DQn.B is 0 V
Pulse duration in forward direction:
DQn.A is 24 V and DQn.B is 0 V
Pulse duration in backward direction:
DQn.A is 0 V and DQn.B is 24 V
