AIN:XQ (Sensor signal type – displacement sensor):
The displacement sensors signal can either be a voltage signal [V, scalable via MIN:XQ and MAX:XQ]
or a current signal [C, 4-20mA].
If the voltage signal at PIN 6 is 0,5V lower than MAX:XQ (at machines off-state) the module switches
to error mode. This function is to see if the sensor scaling is done and if the right displacement
has been choosen in the parameter list.
AIN:XP (Sensor signal type – pressure sensor):
The pressure sensor signal can either be a current signal [C] or a voltage signal [V].
Voltage signals at PIN 14 are not enclosed in the error detection (SENS).
The current signals default range is 4 mA to 20 mA.
The voltage signals default range is 0 V to 10 V.
Further pressure related settings are done with the parameter P_SENSOR, P_NOMINAL and
P_CORR.
CQ:P / CQ:I / CQ:D (PID parameter - displacement control):
CQ:P P gain setting in 0,01 units.
P gain is deactivated with input 0.
CQ:I I gain setting in 0,1ms.
I gain is deactivated with input 0.
CQ:D D gain setting (time factor for differentiation) in 0,1ms.
D gain is deactivated with input 0.
CQ:T1 Filter of D gain in 0,1ms.

The PID parameter tuning will help to optimize the hydraulic system.
