X261 and X262 servo solenoid valves

Connector type:
n = [1, 2] for axis 1 or axis 2
Interface X261/262 is the only interface to the servo solenoid valve and transfers the supply
voltage, setpoint and actual value.
The analog inputs for the valve spool actual value (pin 14 and 15) are differential inputs.
The analog output (pin 7) for the valve spool setpoint is designed for a minimum pin input
resistance of the servo solenoid valve of 5 kΩ.
The supply outputs for the servo solenoid valves (pins 1, 2, 3 and 4) have the following
current rating for the average value of the current for a 10 s load cycle:
● At an ambient temperature of 40 °C: 2.0 A
● At an ambient temperature of 55 °C: 1.5 A
A brief maximum current of 2.5 A is permissible.
The outputs are short-circuit proof.
