5.0 PAR - Setting of parameters for output.
5.1 REV - Selection of direct / inverted output.
0 = direct, 1 = inverted.
Valid selections are 0 or 1.
5.2 DOD - Setting of deadband for e.g. joystick.
The parameter is entered as a percentage of the input span.
Valid selections are 0...99.9%.
5.3 FRQ - Setting of modulation frequency for output current.
The frequency is set in Hz.
Valid selections are 8...400 Hz.
5.4 GA - Setting of I
valve.
The parameter is set in Ampere - with two decimals.
Valid selections are 0...3.00 A
6.0 PRO - Setting of proportional controller
6.1 PF - Setting of proportional factor (Gain)
6.2 If - Setting of integrating factor
At delivery PF is set at 0.15 and IF at 0.5. These settings will work well
for most valves but may have the drawback that it will take too long
before the valve reacts.
In order to optimise the control parameters the following "rule-of-
thumb" can be applied (all other parameters must be set correctly).
1. Connect a DC-coupled oscilloscope direcly across the coil.
2. Set IF at 0.00.
3. Increase PF until the curve on the oscilloscope starts oscillating
constantly.
4. Set PF at half of the above value.
5. Increase IF until the curve on the oscilloscope starts oscillating
constantly.
6. Set IF at half of the above value.
The control parameters PF and IF can now be fine-tuned using the
found values. Lower values will slow the valve’s reaction time but
eliminate any overshoot.
