4.2.2 VLT I/O
Input 27 Quick Stop
Option:
14
Function:
Turns the tension controller ON and OFF. This input should be energized while the line is at zero
speed. The core will be released when this input is not energized. This input is also used to reset
fault conditions.
Function:
Selects the Material Type (PAPER/POLY). Different material types such as paper verses poly require
different Tension loop PID settings and Speed loop proportional gain settings. Changing this input
toggles the values in parameters 19-41 to 19-50. If the PID parameter values are changed this input
must be switch to initiate saving the new values.
Function:
Selects one of two preset core sizes set in parameters 19-05 and 19-06. Core 1 = OFF, Core 2 =
ON. This input is checked when the Diameter Reset (Input 8) in energized and the partial roll select
(Input 4) is not energized. If unwinding, Core 2 can be used as an alternate initial roll diameter, but
Core 1 must always be set for the smallest core diameter used.
Function:
Resets diameter to a new value. If the New Diameter Set (Input 4) is energized, the partial core
diameter value set in parameter 19-04 is used, otherwise the diameter is reset to core1 or core2
values based on Core Select (Input 7).
Function:
Terminal 27 must be closed for the drive to run. If this input is opened while running, the frequency
converter will ramp to a stop at a rate set by the Quick Stop Deceleration time (parameter 3-81).
