Set bit 30 in the parameter Control signals = FALSE/TRUE/FALSE. 40x5050:010 Bit 30
The reference value has now been taught.
g) Move the dancer manually to the upper posion.
The minimum length of material is now saved in the dancer.
h)
Se
t bit 25 in the parameter Control signals = FALSE/TRUE/FALSE. 40x5050:010 Bit 25
The reference value has now been taught.
i) In the parameter Eecve actual dancer posion, check the following:
The upper posion is shown as +100 [%] 40x5052:189
The lo
wer posion is shown as -100 [%] 40x5052:189
The middle posion is shown as 0 [%] 40x5052:189
6.
Check slave operaon at master value.
a) Start the speed-determining drive in the machine with a xed setpoint, e.g. +5 [%] in
the direcon in which the material moves to the rewinder.
b) In order for the third double word to transmit the line speed, the system bus must be
operaonal and the process data in the master have been congured accordingly.
c) Check whether the parameter Actual line velocity, is showing a value = 50.0000
[mm/s]. 40x5051:009
d) In the parameter Control signals, set bit 16 = TRUE and synchronise the winder with
the line speed. 40x5050:010
The ramps can be adapted via Acceleraon to synchronize to line velocity and Decel-
eraon to synchronize to line velocity.
Acceleraon to synchronize to line velocity 40x5051:020
Deceleraon to synchronize to line velocity 0x05051:021
e)
In the parameter Status signals, check whether the ramp phase is complete and
bit 16 = TRUE. 40x5050:110
Velocity actual value must show that the reel motor rotates at -150.8 [1/min] in an
non-inverted motor mount. 40x606C
7. Perform a controller adjustment.
At this point, there must not yet be any material in the machine and the dancer
mus
t be in the lower limit posion. If not, manually move the dancer into the
lower posion.
The diameter connues to be 76 [mm].
a) Set the double word 03 of the control interface "Dancer set Posion" to -90 [%].
b)
Set the double word 04 of the control interface "Dancer control inuence" to 10 [%].
c) In the parameter Control signals, set bit 18 = TRUE and enable the process controller.
40x5050:010 Bit 18
d) Check: The rewinder aempts to rewind material in order to pull the dancer from -100
[%] t
o the setpoint posion of -90 [%] via CCW rotaon of the winding sha.
The speed is the result of 10 [%] system deviaon mulplied by Gain = 1 and the inu-
ence of 10 [%] for approx. 30 [1/min] at d = 76 [mm].
