The parameter "Pulse output
(DQA)" defines the hardware out-
put to use as pulse output chan-
nel.

Output signal
Meaning
Value range
Continuous pulse current at the digital
output PWM DQA
A pulse is output at the digital output PWM
DQA for the set on-load factor and cycle
duration.

Operating mode: Frequency output
In this operating mode you can assign a frequency value with high frequencies more
precisely than by using period duration in PWM mode.
A rectangular signal with an assigned frequency and a constant on-load factor of 50 % is
generated at the digital output.
The frequency output mode has the following functions:
●
When the option "High-speed output (0.1 A)" is activated, you can generate a minimum
pulse duration of 2
μs at a current of 100
mA. If the option "High-speed output (0.1 A)" is
not activated, you can generate a minimum pulse duration of 20
μs with a load >
0.1 A
and a minimum pulse duration of 40
μs with a load of ≥
2 mA and a current of maximum
0.5 A.
If you use a standard output, you can generate a minimum pulse duration of 400 µs with
a load of > 0.1 A and a minimum pulse duration of 500
µs with a load of ≥
2 mA and a
current of max. 0.5 A.

●
You can control the pulse output (DQA) of the channel manually via the control and
feedback interface.
●
You can configure the reaction to CPU STOP. Upon change to CPU STOP, the pulse
output (DQA) is set to the configured state.
