5.2.1 DSM states
The <StatusWord> (0x6041) indicates the DSM state. The following DSM states are possible:
'NOT_READY':
• The electronics circuit has power.
• Device initialization running (e.g. communication interface, hardware, software).
• Device function disabled.
• Hydraulic failsafe spool position (spool position depends on ordered servo valve model).
'INIT':
• Device parameters can be set.
• Device function disabled.
• Communication enabled.
• Hydraulic failsafe spool position (spool position depends on ordered servo valve model).
'DISABLED':
• Device parameters can be set.
• Device function disabled.
• Actual values are available.
• Hydraulic failsafe spool position (spool position depends on ordered servo valve model).
'HOLD':
• Device parameters can be set.
• Actual values are available.
• The selected <ControlMode> (0x6043) is active.
 Chapter "7.1 Control modes", page 127
• The setpoint values from the bus or from the analog input according to the chosen
<DeviceMode> (0x6042) are not effective.
 Chapter "6.2.1 Object 0x6042: Device mode", page 58
• The control loop depending on the selected <ControlMode> (0x6043) is active and the corresponding
pre-defined hold setpoint is used, for example, the <SplHoldSetPoint> (0x6314) for the spool control or
the <PrsHoldSetPoint> (0x6394) for the pressure control.
