6.8.2 Object 0x5E41: Digital output configuration
The behavior of the digital outputs can be configured by the parameter <DigitalOutputConfiguration>
(0x5E41).
Value description
6.8.2.1 Object 0x2420: Digital output 1 type
The <DigitalOutput1Type> (0x2420) is a copy of the <DigitalOutputConfiguration1> (0x5E41) and is used to
be compatible to old firmware versions.

<DigitalOutputType> Description
0 The servo valve's digital outputs are controlled by the parameter <DigitalOutputSetpoint> (0x5E42). The
pin can be used for special purposes.
1 Failsafe spool position monitoring on.
The digital output is controlled by the failsafe monitoring.
 Chapter "7.15.5 Failsafe monitoring", page 241
2 Error output pin. The servo valve's digital output acts according to the Device Profile Fluid Power. This
means it is controlled by the device state machine (fault indication). In this case the digital output is used
to indicate fault states (negative logic).
 Chapter "5.2.2.5 Error output pin", page 52
3 Enable Acknowledge. The digital output gets high (24 V) if the servo valve device state machine (DSM)
state is 'ACTIVE' (supply voltage is > 18 V, digital enable input is high, no fault will force the DSM to fault
state, …).
4 Control Deviation Monitoring. The digital output gets high (24 V) if the 'control deviation bit 11' of the
<StatusWord> (0x6041) is low. That means there is no control error.

WARNING
Moving machine parts!
The word "failsafe" means not a personnel safety. Parts of the machine can move if the servo valve has a
fault.
 If a personnel safety is needed, some additional electrical and hydraulic parts are necessary!
The availability of the digital output 1 (error output pin) depends on the servo valve model.
