Impulses Impulses Impulses Impulses Impulses—The number of impulses per encoder revolution (encoder-
specific). This value must be entered in either millimeters or
inches. If this value is changed, the unit must be turned off and
then on again to activate the change.
mm (inches) mm (inches)
mm (inches) mm (inches)
mm (inches)—Enter the number of encoder pulses per length of parent
machine travel. (Optimum: 1 impulse = 1 mm or 1/100 inch of
product travel) Changing this setting may alter the maximum
speed capacity and resolution of the MCP-25. (If this value is
changed, turn the unit off and then on again to activate the
change.)
The ratio should be as close to 1:1 as
possible. If this ratio is obtained, the
control can operate at speeds up to
6500 feet/min (2000 m/min). Since the
accuracy of the control amounts to 1
impulse or less, the maximum possible
deviation is therefore 1 mm or less.
This accuracy can be increased if the
resolution of the encoder is less than 1
mm (one encoder impulse corresponds
to less than 1 mm of product travel).
However, the maximum possible speed
(Vmax) required with this accuracy
equally reduces the ratio. The Vmax
parameter and the resolution change
automatically.
Vmax Vmax Vmax Vmax Vmax—The maximum speed at which the accuracy and resolution of
the encoder are maintained. (Displayed information only. Cannot

Resolution—Resolution of encoder impulses. (Displayed information

Direction recognition Direction recognition Direction recognition Direction recognition Direction recognition—If the direction recognition function is activated,
gluing is only possible in one direction of the parent machine. In
addition, an encoder with an A+B signal output is required. Note
the installation orientation of the encoder.
The direction recognition function is not
available when using a VCE type
encoder.
