Moog ACV with CANopen bus interface 5 Device control

Local mode

B99224-DV018-D-211, Rev. A, October 2018 45

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.

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).
