4. PROGRAMMING WINGING PARAMETER
4.1. MEMORY RANGE SELECTION
CNC-210A contains 1000 memory step, by defining the region, users can effectively manage the
memory. Various winding parameter can be stored in different regions and can be retrieved
instantaneously. After specifying the regions, programming and winding can be done in those
regions;all un-selected regions will retain their original contents and unmodified. When setting
the STEP number, the Ending step number must be larger than the Starting step number, or the
winding operation will not start

Specifying starting step
In ready mode, press to selected. [Setting range 0 ~ 999].

Specifying ending step
In ready mode, press to selected. [Setting range 0 ~ 999].
4.2. Programming winding parameter
In READY mode, press invokes the programming mode, the STEP DISPLAY shows
START STEP, the parameter indicator
『SHIFT』
lit, the DATADISPLAY shows SHIFT setting value,
the SHIFT can be changed by pressing the numerical keys followed by the key.
After that the STEP number will automatically increase by one, to continue set the SHIFT for next
step. When the STEP number is larger then the END STEP , the STEP number will restore to the
START STEP and the indicator light will change from『SHIFT』to『WIDTH』to specifying the
width for each STEP. Repeat the same procedure using numerical keys and the key, all
winding parameters for each STEP can thus programmed, after that press key again to go
back to ready mode.
The following functions are also available:
：
To select guiding direction, forward or reverse.
：To select winding direction, clockwise or counter-clockwise.
：To specify whether to suspend winding when the guiding traverse moves to the two edges
of the width.
：To select whether guiding traverse returns to the starting position automatically or upon a
manual pressing of the key.
：Select whether to have auto-starting function for each step.
：Clear the current value to zero.
：Copy the content of the previous step to the current step.
：Go back to the previous programming step.
：To scroll through different parameters.
Each time when change the PARAMETER or OPTIONS, key must pressed to effect the
change.

4.3. Guiding traverse shaft introduce setting
During set the
『SHIFT』
,
『WIDTH』
and
『guiding traverse travel limit』
, can use numeric keypad
to set location data or can also use ,keys to leading the guiding traverse shaft location.
4.4. Clear all winding parameter
In the READY mode, press will clear all the winding parameter in the memory. Be
cautious in using this function or all the data will be lost.
5. WINDING METHOD DESCRIPTION
Prior to winding, the general winding principles are explained below so the operators can have a
better understanding of the performance of the controller and make better use of it.
5.1. Counting mode

Absolute counting mode
Winding spindle shaft is capable of fixed-point stopping. Upon each restart, the turn count will
reset only the integer portion of the turn’s to zero, with the decimal unchanged. For example,
for a previous number of 100.3 turns, when restarting the next step winding, the counting will
start with 0.3 to avoid accumulation of spindle shaft free play error from consecutive windings.
This counting method may cause insufficient winding by one turn. Therefore, when starting
from 0.9, the spindle will turn to the 0.0before it starts counting.

Relative counting mode
This counting method zeros the counter upon each restart, therefore it is easy to understand
and will not cause insufficient winding.
5.2. Wire-guiding mode

Interlace wire-guiding
If the『WIDTH』of the step is zero, the wire-guiding becomes interlace mode. When it begins
winding, the wire-guiding will follow the wire direction to proceed two wire diameters and
regress one wire diameters cyclically until the step of winding ends. This mode especially suits
the inductor winding.

Non wire-guiding
Sometimes, the winding device may be used to winding adhesive tapes or copper foil. When
the wire-guiding is not needed, 『PITCH』may be adjusted to zero and the wire-guiding won't
be move.
5.3. Operation mode

Single click mode
When press the start switch, the motor start winding, and when you release the start switch,
the motor stop winding immediately.

Double click mode
When press the start switch, the motor start winding, and if you want to pause the motor, you
have to release the start switch then press it again.

TAILY AUTOMATION CO.,LTD.
5.4. Running mode

Continual mode
Before it begins winding, if『SHIFT』of the step set as 999.99, then the starting position, the
width , the wire-guiding direction and the winding direction won't be re-read. The values are not
changed, that is the wire guiding will continue guiding wires on the same position. The width
and left-right margins are the same as the ones of the previous section. Both the wire-guiding
and winding directions are not changed either. This mode especially suits to winding which
have the multiple drawing tops in the same sets of coils.

Edges slow mode
The winding speed will slow down before the guiding traverse reach to the two edges of the
width (work with『E. SLOW』turns). After the guiding traverse veered, then restore to hi-speed
winding. (Refer to the section 7.1. edge slow mode).

Automatically circularly mode
If key set to on, it means Automatically circularly mode, in this mode when finish a step of
winding it will automatically get into next step and start winding without press key (work
with and keys).
5.5. How to set winding turns accurately

Preset method
Set the 『E.SLOW』 to zero first and then set the 『TURNS』 to the desired number. Set proper
parameters according to copper wire, bobbin, tension, etc, then press to start winding.
When finished, obtain the actual number of turns and calculate the number of overshot turns.
Go into programming mode and subtract the number of the overshot turns from the 『TURNS』
to obtain the required setting.
This method has a higher throughput, however, the resulting stopping location may not be
precise.

High-Low speed method
This method uses a combination of 『H.S』/『L.S.』and 『E.SLOW』to achieve the desired
number of turns.
The
『L.S.』
should not be too high. The number of『E.SLOW』 turns must be adequate to allow
the spindle shaft to slow down to low speed before reaching the total number of turns. This can
result in precise stopping location.

Double-brake method
As the winding turns of the winding shaft reach the numbers of the『E.SLOW』,brake for a
short period first. After the winding shaft stops, continue winding at low speed. Therefore the
numbers of the slow speed may be reduced and the efficiency of winding may be increased,
(Refer to the section 7.1. braking mode).

9.2. Adjustments for CNC-210AE

Speed Mode selection
To select the speed signal output mode for winding driver.
Selected by JP1.
1. V-out mode：Represents the speed signal with DC 0~10v output.
2. H/L mode：Represents the speed signal with HI/LOW lever output.
Hi speed with HI lever, low speed with LOW lever.

V-out adjust
1. Set the winding parameter H.S., L.S. in 99, and press key to change the DISPLAY shows
RPM. Then press key to start winding.
2. Rotate V-out potentiometer to make the winding speed (RPM) as you want.
Then press key to stop winding.
3. This function only worked in Vout mode.

10.2. Periodically maintain

Please periodically clean up the controller inner accumulate dust and dopants.

Please periodically check the wire connection between controller and machine if have loose or
bad contact.

The following parts must be maintained or changed periodically as list below. If any part is
found faulty, it must be changed immediately even when it has not yet reached the end of its
life, which depends on the operating method and environmental condition.

For parts replacement, please contact your sales representative.

10.3. Error message
When a fault occurs during operation, the DATA DISPLAY shows error massage, stop winding
and then RESET go back to the READY mode.
Err-0：The parameters or data in memory are fault.
Err-1：The『SHIFT』value sets exceed the Travel Limit.
Err-2：During winding, the guiding traverse to exceed the Travel Limit.
Err-3：During winding, the guiding traverses reach to the Home sensor.
Err-5：RS-485 communication error.
Err-p：Password error, key in 4 numbers password before edit.
10.4. To abort seeks the original position
At boot and reset procedures, if because of unknown reason however engender the winding
shaft and guiding traverse can't find out the original position and make the controller can't get into
ready mode, can press key to abort seeks the original position, make controller get into ready
mode.
10.5. Troubleshooting
This section provides information to guide the user in understanding different fault condition and
their general troubleshooting procedures, and with their possible solutions.

