Maximum output slope: Minimum time for the maximum
excursion of the head (from all open to all close). It allows us to
define a ramp for the maximum variation of the analog output. In
this way very fast movements of the head are not allowed. If the
time is 0 every movement is free. With a value of 1 second, for
example, the position command increment will be 20000 mV/s.
Every movement will be performed according to the calculated
ramp.
Feedback actuator: Select if the actuator has a feedback transducer (intelligent actuator).
Vout Min/Vout Max: (only if feedback actuator is YES). It allows to choose between which values the intelligent
actuators has to work. The default parameters are 0 / 10000 [mV]
KP gain: Proportional gain. Range: 0...10000.
KI gain: Integral gain. Range: 0...10000.
KD gain: Derivative gain. Range: 0...10000.
Divisor: It allows to choose the divisor of the formula to calculate the output command: the divisor allows to insert
the parameters PID with different resolutions.
OUT = (KP * DEV + KI * (integral add DEV) + KD * (derivate DEV)) / DIV
DEV=Actual Value[%] - Setpoint[%]
Calibration Mode 100%= 20000 mV
Work Mode 100%= Vup – Vdown
Dead band positive: Value added to the output already calculated by the PID controller to compensate the positive
dead band. Range: 0...+5000 mV or max value mA.
Dead band negative: Value subtracted from the output already calculated by the PID controller to compensate the
negative dead band. Range: 0...+5000 mV or max value mA.
Start delay time: delay time on movement starting (1). The second time (2) refers to the profile 2 with alternate
profiles.
4.6.6 Head Setup for PWDS
The setup page for channels managing the PWDS function is almost identical as the one for normal parison
control: the only difference is that the configuration of the die type, with the four big icons in the middle of the
page, is not present; for the same reason also the function keys F3 to F6 are gray.
Also the second Start delay time, the one used in case of alternated profiles, is not present
