5.2.2.5 Error output pin
The error output (digital output 1) is used to indicate fault states (negative logic) according to the Device
Profile Fluid Power.
• Digital output 1 is set to 1 on power on (TR1) of the servo valve.
• When a fault is detected (TR8) the digital output 1 is set to 0 to indicate a fault (negative logic).
• When a fault state is left (TR10, TR11) the digital output 1 is set to 1.
To enable this behavior on the digital output 1, the parameter <DigitalOutputType1> (0x2420) must be set
to 2.
