Description
ARTDrive V2 series - Instruction Manual Chapter 6 Parameter • 303
By setting the source of O06.05 - DiaClc start src to one and if the Drive is enabled, the
procedure is started.
During this phase the parameters and the PI and PD regulators are disabled.
The regulation checks the signal coming from the dancer potentiometer.
If this value is higher than the one set in Max deviation, the motor starts rotating with the
speed reference set in Positioning spd in order to wind the material on the winder and to
bring the dancer into its central working position.
If the regulation checks that the signal coming from the dancer potentiometer is lower
than the value set in Max deviation, the motor starts rotating with the speed reference set
in Positioning spd in order to unwind the material and to bring the dancer to the point
identified by Max deviation.
At this point the reference is inverted till bringing the dancer in its central working
position.
When the dancer has reached its central position, the O03.44 - PID PI out parameter is
initialized with the value of the measured diameter.
The Diacalc active variable brings to a high logic level the Diam Calc act digital output,
stating the end of the diameter calculation phase.
Now, if the PI and/or PD blocks are enabled, the system reaches automatically
the regulation mode.
To this purpose the digital inputs programmed as DiaClc start for the PI and PD enable
are brought simultaneously to a high logic level.
The Diacalc active output signal can be used to reset the DiaClc start command (such
command is activated on the climbing leading edge of the digital input; for this reason it
has to be brought to a high level after power supplying the Drive regulation section and it
has to be reset when the starting calculation phase is over).
The value of O03.44 - PID PI out is calculated via the following formula:
PID PI out = (Minimum diameter x PI clamp top) / value of the calculated diameter
The O03.28 - PI clamp top and O03.28 - PI clamp bot parameters of the PI controls
menu have to be set according to the maximum and minimum winder diameter.
