2Basic Commissioning
Through this section, you can quickly know the following basic commissioning
processes for Integrated CNC System for Shoe Molding Machines:
1. Set commissioning parameters.
2. Adjust the axis direction.
3. Return to the machine origin.
4. Define the workpiece origin.
2.1 Set Commissioning Parameters
The integrated CNC system supports both the bus control system and the non-bus
control system.
To set the type of control system, press → 1→ F4, modify the value of
parameter N50000 Control System Type.
2.1.1 Set the Bus Control System
This operation is used to set commissioning parameters for bus control system.
Before setting commissioning parameters for the bus control system, ensure the
following:
•Parameter N50000 Control System Type is set to 1.
•The used terminal board is Lambda 5M RJ45.
To set commissioning parameters for the bus control system, do the following:
1. To enter Param functional area, press .
2. To enter Axis Interface, press 2.
3. Find and set the following axis parameters:
–N11000 Encoder Feedback
–N11020 Axis Encoder Type

2.1.2 Set the Non-bus Control System
This operation is used to set commissioning parameters for the non-bus control
system.
Before setting commissioning parameters for the non-bus control system, ensure
the following:
•Parameter N50000 Control System Type is set to 0.
•The used terminal board is Lambda 5S.
To set commissioning parameters for the non-bus control system, do the following:
1. To enter Param functional area, press .
2. To enter Axis Interface, press 2.
3. Find and set the following operation parameters:
–N11000 Encoder Feedback
–N11020 AXis Encoder Type
–N74020 Coarse Positioning Dir.
–N74030 F in Coarse Positioning
–N74050 Fine Positioning Dir.
–N74060 F in Fine Positioning
–N74100 Lead Screw Pitch
–N74130/N74140 Mechanical Reducer Ratio
See Parameter List for details.
2.2 Adjust the Axis Direction
This operation is used to check if the positive direction of each axis is the same with
the direction specified by Right Hand Rule, and adjust it if not, so as to avoid
damage to the machine tool due to incorrect direction.
Taking X-axis as an example, to check the axis direction, do the following:
1. Press → 2→ F8 and check the value of parameter N10000 Axis
Direction(X):
–1: positive
–-1: negative
2. Judge the positive direction of X-axis according to Right Hand Rule.

12 /33
3. In JOG / Handle / Step mode, press X+ to move X-axis, and observe its moving
direction.
4. Optional: If the actual moving direction is opposite to the judged direction,
modify the value of parameter Axis Direction(X) to the opposite value.
Example
The current value of parameter Axis Direction(X) is 1. And you find X-axis moves
towards the negative direction after pressing X+.
Then, you need to change the value of the parameter to -1.
2.3 Return to the Machine Origin
This operation is used to adjust the coordinate position before machining.
According to the encoder type, it can be divided into the following:
•Return to the machine origin with an incremental encoder.
•Set the datum with an absolute encoder.
To set the encoder type, press → 2→ F8, input the manufacturer password,
and modify the value of parameter N11020 Axis Encoder Type.
2.3.1 Return to the Machine Origin with an Incremental Encoder
This operation is used to return to a fixed point, i.e. machine origin, assigned by
design, manufacturing and debugging before the machine tool leaves factory.
Before returning to the machine origin with an incremental encoder, check the
motor nameplate and ensure the value of parameter N11020 Axis Encoder Type is
set to 0.

To return to the machine origin with an incremental encoder, do the following:
1. In REF mode, to enter Coor interface, press → 1:
2. Press one of the following:
–F1: return X-axis to the machine origin.
–F2: return Y-axis to the machine origin.
–F3: return Z-axis to the machine origin.
–F5: return X-axis and Y-axis to the machine origin at the same time.
–F8: return all axes to the machine origin in order of Z-axis, X-axis and Y-
axis.
Note: The system entitles Z-axis the highest priority in returning to the machine origin by default.
For safety, it is suggested to firstly return Z-axis and then return X-axis and Y-axis at the same time.
After returning, the sign appears in front of related axes in the coordinate
display area.

2.3.2 Set the Datum with an Absolute Encoder
This operation is used to return to the machine origin with an absolute encoder by
directly setting the datum at the first time to use the system.
Compared to returning to the machine origin with an incremental encoder, it owns
the following advantages:
•No need to set returning orders for all axes in datum setting process.
•No need to return to the machine origin again after restarting the system, and
recovering from power interruption and E-stop because the system will
automatically read the datum information.
Note: You need to set the datum again after replacing battery of the absolute encoder.
Before setting the datum with an absolute encoder, do the following:
•Check the motor nameplate and ensure the value of parameter N11020
Encoder Type is set to 1.
•Set the values of WISE drive parameter Pr015 Absolute Encoder Setting to 0,
and software parameter N11000 Encoder Feedback to Yes.
To set the datum with an absolute encoder, do the following:
1. Taking Z-axis as an example, to set the datum with an absolute encoder for Z-
axis, do the following:
1. Manually move Z-axis to the fixed position of the machine tool.
2. In REF mode, press → 1→ F7.
3. Press F3.
The system automatically reads and records Z-axis machine coordinates.
And the sign appears in front of Z-axis in the coordinate display area
after successfully setting datum.
2. To set the datum with an absolute encoder for the other axes, repeat step 1:
–F1: return X-axis to the machine origin.
–F2: return Y-axis to the machine origin.
–F5: return X-axis and Y-axis to the machine origin at the same time.
Note: F8 means returning all axes to the machine origin in order of Z-axis, X-axis and Y-axis.
3. Restart the software to validate the setting.
Note: Because of time sequence, it takes time for the software to read absolute data, possible resulting in
interface choking in datum setting.

After setting the datum with an absolute encoder, you can export the set datum by
pressing F1 in the next page to save it to the root directory of a USB flash disk. When
a new software is installed, you can import the previously saved datum by pressing
F2 in the next page, so as to save the trouble of repeated setting.
2.4 Define the Workpiece Origin
Based on a certain point on the workpiece, this operation is used to define the origin
of workpiece coordinate system (Hereinafter referred as to WCS ). Namely, it is fixed
relative to the certain point and mobile relative to the machine origin.
The selection of workpiece origin should meet the conditions of simple
programming, simple dimensional conversion, and small machining error, etc.’
If Machining Setting is set as double-axis mode, you need to separately do
centering for X1-axis and X2-axis. At this time, the other axes should be still.
To define the workpiece origin, do the following:
1. In Handle mode, to open Line Centering dialog box, press → 1→
→ F2:
2. To select the target workpiece coordinate system, press .
3. Optional: Set the spindle speed during centering in S in Centering input box.
A large value is not suggested. And it is set to 500 RPM by default.
4. Optional: To enable edge finder for accurate centering, press F6:
5. Move X1-axis to one side of the workpiece and X2-axis to the other side, and
press F1.
The system automatically records the coordinates of X1-axis and X2-axis.

16 /33
6. Exchange positions of X1-axis and X2-axis and press F2.
The system automatically calculates the midpoint coordinate of X1-axis and X2-
axis separately based on the coordinates of X1-axis and X2-axis recorded in
step 5 and step 6, and separately sets the midpoints of X1-axis and X2-axis as
their workpiece origins.
Note: In single-axis mode, if you press F1 or F2, operations are only effective to X1-axis or X2-axis.
7. According to step 5 and step 6, set the the workpiece origin of Y-axis and press
F7 in Coor interface.
X-axis and Y-axis move to the workpiece origin specified by centering and Z-
axis is on the upper limit of workbench travel.
3Quick Start
Through this section, you can quickly know the following machining processes for
Integrated CNC System for Shoe Molding Machines:
1. Load a program file.
2. Adjust the WCS.
3. Calibrate after tool changed.
3.1 Load a Program File
A shoe mold has multiple faces, and each face corresponds to a program file.
