Bit 10: Axis install mode negative direction
If the servo valve is in <DeviceMode> (0x6042) = 3 (Install mode) or <DeviceMode> (0x6042) = 4 (reference
mode), then the hydraulic axis can be moved with bit 10 of the <ControlWord> (0x6040) in negative direction.
The velocity of the movement is defined in the parameter <ManualMaxSpeed> (0x5614). If an incremental en-
coder is used to measure the axis position then <DeviceMode> (0x6042) = 4 (reference mode) is used to run
the homing position to calibrate the incremental encoder.

Bit 15: Ramp stop
If this bit is set, the spool position ramp and the pressure ramp output are frozen.

Value description
Same values as <ControlWord> (0x6040)
5.1.4 Object 0x403F: Local control word default
The <LocalControlWordDefault> (0x403F) defines the control word after power up of the digital servo valve.
During startup of the servo valve, the parameter <LocalControlWordDefault> (0x403F) is copied to the param-
eter <LocalControlWord> (0x4040).
