5.5 Operation modes
The setting of parameter <E00> is determining which operation mode is activated. This parameter is factory preset!
Only the mode relevant parameters are made available for each of the modes.
Available operation modes:
Figure 8 : Available Operation Modes
With the use of parameter <E00> any basic mode of operation may be selected. A change in operation modes will be
effective immediately. Recalling the parameters for the newly chosen mode takes only a few seconds. During this time, the
display flashes. Only the mode relevant parameter are made available.
<E00>
Mode description
1
Open loop, 1 proportional valve with 2 solenoids without feedback
2
Open loop, 2 proportional valves with 1 solenoid each without feedback
3
Closed loop valve, single, 1 proportional valve with 2 solenoids and feedback of spool position
4 Closed loop process, single, 1 proportional valve with 2 solenoids and feedback of process value (position,
velocity, pressure, force, torque etc.)
5
Reserved
6 Closed loop valve and process, double, 1 proportional valve with 2 solenoids and feedback of spool position
and additional feedback of process value (cascaded controller)
7
Reserved
8 Closed loop processes, double, 2 independent proportional valve with 1 solenoid each and feedback of two
independent process values (e.g. two pressure control systems)
9
Reserved
10 Controller function without valve, control of 1 process value; provide set value to follow up electronics (e.g.
valve with integrated electronics, frequency converter for AC motor etc.)
11 Controller function without valve, control of 2 process values (cascaded controller, e.g. position and velocity
controller); provide set value to follow up electronics (e.g. valve with integrated electronics, frequency converter
for AC motor etc.)
