7.18.2.1 Object 0x3103: Frequency
This parameter defines the function generator output signals frequency which is multiplied with the frequency
prefix factor to get the function generator output signals frequency in Hertz [Hz] or [1/s].
7.18.2.2 Object 0x3108: Frequency prefix
This parameter defines a factor which is multiplied with the parameter <FunctionGenFrequency> (0x3103) to
get the function generator output signals frequency in Hertz [Hz] or [1/s].
Value description
7.18.3 Function generator output signals
The function generator output signals can be used for several tasks. An important one is the use as the set-
point for the servo valve. This can be done by mapping the output signal to one of the following servo valve
setpoint inputs:
•
Spool position setpoint value:
<SplSetpointParameter> (0x3320)
Chapter "6.2.3.2 Object 0x3320: Setpoint parameter", page 60
•
Pressure setpoint value:
<PrsSetpointParameter> (0x3310)
Chapter "6.2.4.2 Object 0x3310: Setpoint parameter", page 62
7.18.3.1 Object 0x3101: Output signal
This is the function generator output signal.
