Chapter 3 Debugging Instructions

3.1、Functional allocation

The SD600-E series servo drive is equipped with a cutter shaft, film feed shaft, feed shaft and single servo function. The function of the corresponding drive can be assigned by the position control mode command source selection (Pr2.00).

The function of the drive is set by setting the value of Pr2.00 through the drive operation panel. The parameters related to this model are set as follows:

When Pr2.00 = 3 is set, the function corresponding to the cutter axis is operated;

n Pr2.00 = 4 is set, the function corresponding to the film feeding axis is operated;

When Pr2.00 = 5 is set, the function corresponding to the feed axis is run.

After the change is complete, the drive needs to be powered back on.

3.2、System parameter setting

3.2.1 Tool Axis Parameter Setting

According to the mechanical parameters, the cutter shaft circumference, the number of tools, the cutter shaft transmission ratio numerator, and the cutter shaft transmission ratio denominator are set.

Sync zone width: The sync zone refers to the area where the cutter speed is equal to the feed speed. This parameter can be set according to the actual synchronization angle.

The midpoint of the origin offset: the offset angle between the tool origin and the midpoint of the sync area. By adjusting the value, you can change the time that the cutter enters the sync area.

Origin offset tangent point: refers to the offset angle between the knife origin and the cutter closure. Internal angle calculations are based on this value.
Cam correction range: the first value is the cam correction minimum value and the second is the cam correction maximum value. When the sync area deviates, the correction is performed according to these two values. Setting the first value is smaller, the more accurate the correction, but the setting is too small, which will result in frequent corrections.

When the second value is set to a large value, it can be quickly corrected, but the cutter speed and the film feed speed are less synchronized.

3.2.2 Membrane Axis Parameter Setting

The film roll circumference, the film shaft drive ratio and the film shaft drive ratio denominator are set according to the mechanical parameters.
Film roll circumference: The length corresponding to one rotation of the film roll.

3.2.3 Cutter to Fork Distance, Cutter to Color Scale Distance

Through the distance from the cutter to the fork and the distance from the cutter to the color scale, the material level and the cutting point of the current bag length and material length can be calculated.

1、Distance from cutter to fork:

When the material origin sensor signal is valid, we could measure the position where the cutter is closed to the first fork as shown.

2、Distance from the Cutter to the Color Scale:

The distance the cutter closes to the color sensor.

3.2.4 Shaft Parameter Setting

According to the mechanical structure, set the circumference of the shaft, the length of the fork, the molecular ratio of the shaft drive, and the denominator of the shaft transmission ratio.

Chapter 4 Maintenance and Testing

4.1 Alarm processing

The system has an automatic alarm function. When the operation is improper or the machine is abnormal, an alarm screen and a prompt will pop up, and the staff can adjust or repair according to the prompt of the screen.

(1) Tool axis origin loss alarm:

The cutter origin signal was still not detected within one and a half rotations of the cutter. The “Tool Axis Origin Alarm” window pops up on the touch screen and the whole machine stops. Detect the origin sensor of the tool axis.

(2) Color code loss alarm:

In the color code tracking mode, when the color code loss exceeds the number of lost alarms, the touch screen pops up the “color mark alarm” window to detect whether the color code signal is normal.

(3) Material origin loss alarm

When the shaft sensor signal loss exceeds the maximum number of material origin stops. The touch screen pops up the “Material origin alarm” window, and the whole machine stops. Detect the material origin sensor.

(4) Continuous electronic anti-cutting alarm

When the electronic anti-cut detection detects two packs of continuous cutting, the touch screen pops up the “continuous electronic anti-cut alarm” window, and the whole machine stops. The material is shifted, and the material is directly turned on after finishing the material.

(5) Cutting alarm

When the tool axis runs within the set anti-cut angle and the current torque continues to be greater than the torque anti-cut limit value, the touch screen pops up the “cutting alarm” window, and the whole machine stops. Among them, the duration is the torque anti-cut filter value. If the material is cut, it is observed whether the material is also shifted. If there is no shift, it will be turned on directly. If the material is not cut, adjust the torque assignment or the torque protection filter value.

(6) Measuring bag length alarm

During the length measurement period, if there is still no color mark in the maximum bag length (Prc.39) of the automatic film measurement, the touch screen pops up the “measurement bag length alarm” window, and the film servo stops. Check if the color code signal is normal, and check whether the set value of the film axis (Prc.39) is smaller than the current bag length. The default value of Prc.39 is 500.0mm.

(7) Membrane servo alarm

According to the display code, check the explanation of the fault code corresponding to the "SD600A-SMM Series AC Servo System User Manual".

(8) Knife servo alarm
