6.2 Setpoint value path
The setpoint values for pressure, spool position, axis position, axis velocity and flow can be received via the
field bus or via the analog/encoder inputs. The axis setpoints (position, velocity and flow) are only available in
axis control valves.
• The spool position setpoint value received via bus is provided by the parameter <SplSetpoint> (0x6300).
• The pressure setpoint value received via bus is provided by the parameter <PrsSetpoint> (0x6380).
• The axis position setpoint value received via bus is provided by the parameter <PosSetpoint> (0x6600).
• The axis velocity setpoint value received via bus is provided by the parameter <VelSetpoint> (0x6500).
• The flow setpoint value received via bus is provided by the parameter <FlwSetpoint> (0x5300).
• The spool position setpoint value from local source is coming from the analog input 0
<AnaInpActualValue0> (0x3204).
• The pressure setpoint value from local source is coming from the analog input 1
<AnaInpActualValue1> (0x320C).
• The axis position setpoint, axis velocity setpoint and the flow setpoint values from local source are not
referenced to a special hardware input.
Which setpoint is in effect depends on the parameter <DeviceMode> (0x6042) and the <StatusWord>
(0x6041):
• <DeviceMode> (0x6042) is set to 1 (setpoint input via bus), <StatusWord> (0x6041) is 0111
b
('ACTIVE'):
The setpoint value received via field bus is forwarded to the demand value generator.
• <DeviceMode> (0x6042) is set to 2 (setpoint input locally), <StatusWord> (0x6041) is 0111
b
('ACTIVE'):
The setpoint value coming from the analog input is forwarded to the demand value generator.
• <StatusWord> (0x6041) is 0011
b
('HOLD'):
The hold setpoint values are taken as setpoint values. This hold setpoint is in effect regardless if the de-
vice mode <DeviceMode> (0x6042) is set to 1 (setpoint input via bus) or <DeviceMode> (0x6042) is set
to 2 (setpoint input locally).
The spool position hold setpoint value is stored in the parameter <SplHoldSetpoint> (0x6314). The pres-
sure hold setpoint value is stored in the parameter <PrsHoldSetpoint> (0x6394). In the same manner the
setpoints for the axis position, velocity and flow are stored in the parameter
<PosHoldSetpoint> (0x6614), <VelHoldSetpoint> (0x6394) and <FlwHoldSetpoint> (0x5313).
