- If the same analog measuring system which is used for the angle also used for the angle Cutting length, then it is necessary, set the values for the cutting length calculation.
- Setting values with minimum angle: Place the cursor in the first row and first column of the table (line: min; column: S. Beg). Now, enter the smallest possible cut angle. Let down the cutting blade to beginning of the cut (till the point, where the upper beam and lower beam of the scissors just touch) and press the F2 key. Now place the cursor on the field in the first row and second column (row: Min; column: S. End) and let down the cutting blade to the end of the cut. Now press the F2 key again. Thus the values for the minimum angle are set up.
- Setting values with maximum angle:
- Place the cursor in the second row and second column of the table (line: max; column: S. Beg). Now, enter the biggest possible cut angle. Let down the cutting blade to beginning of the cut (till the point, where the upper beam and lower beam of the scissors just touch) and press the F2 key. Now place the cursor on the field in the first row and second column (row: Max; column: S. End) and let down the cutting blade to the end of the cut. Now press the F2 key again. Thus the values for the maximum angle are set up.Configuration of inputs and outputs

6.2.3.1. Analog parameters
Velocity
The maximum speed is set in this register, in rpm. The speed is monitored by the encoder speed (0 –
10000 rpm). Should there be gearing between the motor and the encoder this has to be considered
in the calculations.
EXAMPLE!
Demanded motor speed rpm = 3000
Gearing ratio i = 10
V = RPM/i = 3000/10 = 300
Edge multiplier and impulse multiplication factor has not to be considered.
Acceleration
The acceleration during positioning in revolutions per second squared is set in this parameter.
P-portion
Proportional amplification: setting 1…..3000
General:
The P-controller exclusively consists of a proportional portion and has thereby its characteristics. In
principle the p term multiplies the input value by a coefficient.
P40:
By offset the difference between the demand and actual value is multiplied by the entered value and
shown as power-sharing. The bigger the proportional amplification the more sensitive the control
loop will be (possibly even unstable).
I-portion / I-Limit
Integral step: setting 1….1000
General:
An I-controller (integrating controller) provides the control value through timed integration of the
offset taking the reset time into account. A continuing offset leads to further increase of the analog
output. The reset time determines how big the temporal influence is. The maximum reset time is
limited by I-limit. The step response of the I-portion is a linear increase. That means for a constant
offset the integral will be increased and thus reinforces the I-portion.
P40:
By offset the analog control voltage will continue to increase step by step until there is zero
difference between demand and actual position and the entered I-limit in this register is reached
respectively. The greater the I-portion, the slower is the response.
