Valve output
Activation with
Pulse width modulation (PWM): Command values are implemented by the actuator
with an equivalent pulse-width-modulated switch signal at the valve output.
Command value limiting value: The constant command value is converted into a
switching output signal, depending on a configured limiting value.
Open valve from a command value limit-
ing value of
In the 1-byte command value data with limiting value evaluation, the received con-
stant command value is converted into a switching output signal, depending on the
limiting value configured here. The valve drive opens when the command value
reaches the limiting value or exceeds it.
This parameter is only available in the case of "activation with command value limit-
ing value".
Close valve if command value limiting
value (hysteresis) falls below
In the 1-byte command value data with limiting value evaluation, the received con-
stant command value is converted into a switching output signal. A hysteresis is also
evaluated to prevent constant closing and opening of the actuator for command val-
ues in the area of the limiting value. The valve drive only closes when the command
value undershoots the limiting value minus the configured hysteresis.
This parameter is only available in the case of "activation with command value limit-
ing value".
