
Ramp Compensation allows tuning of adhesive amounts during acceleration and deceleration of
main machine to reduce waste and increase machine efficiency by entering appropriate
parameters.

The colored parameters are related to the different phases of the main machine (see colored
graph). A higher value will result in a higher compensation (more glue amount during
acceleration, less glue amount during deceleration).

After setting parameters by visibly checking the product result, further fine tuning might be
necessary by checking products from the acceleration/deceleration ramp in a lab.
Item Description
1
Glue Amount Compensation Curve
• (PreC) Precompression Time
in seconds: When using ramp compensation without
pressure control loop, this defines the time the system will pre-compress at 75% pump
speed before adhesive application.
• (Accel) Compensation for Acceleration Ramp
in % or rpm: This is the added percentage
or rpm of pump speed to compensate the main machine acceleration ramp.
• (Delay) Damping Time
in seconds: within this time the compensation is reduced to the
normal application rate in order to prevent an elastic impact.
• (Corr) Glue Amount Correction Factor
in %: Allows an adjustment of pump speed if a
speed correction is required due to measured deviations of the adhesive amount.
• (Decel) Compensation for Deceleration Ramp
: This is the subtracted percentage or rpm
of pump speed to compensate the main machine deceleration ramp.
By pressing the appropriate button you can edit the value by means of numeric entry keypad.

Ramp Detection Threshold for deceleration in %/1s
A main machine deceleration phase is automatically detected when its speed change lies
above the given value.
By pressing the input field you can edit the value by means of numeric entry keypad.
6
Ramp Detection Threshold for acceleration in %/1s
A main machine acceleration phase is automatically detected when its speed change lies
above the given value.
By pressing the input field you can edit the value by means of numeric entry keypad.
