Clear all winding parameterIn the”READY”mode, press will clear all the winding parameter inthe memory. Be cautious in using this function or all the data will be lost. 5. WINDING METHOD DESCRIPTIONPrior 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(Refer to the section 7.1. Counting mode).◆Absolute counting modeWinding 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 turn 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 0.5~0.9, the spindle will turn to the 0.0 before it starts counting.◆Relative counting modeThis 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-guidingIf the『幅宽』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-guidingSometimes, 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(Refer to the section 7.1. Operation mode).◆Single click modeWhen press the start switch, the motor start winding, and when you releasethe start switch, the motor stop winding immediately.◆Double click modeWhen 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.5.4. Running mode◆Continual modeBefore 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 modeThe 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 traverseCNC-220S USER MANUAL VER. Page 8 of 18迈维自動化有限公司maiwei AUTOMATION CO.,LTD.veered, then restore to hi-speed winding. (Refer to the section 7.1. edge slow mode).◆Automatically circularly modeIf key set to on, it means Automatically circularly mode, in this modewhen 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 Correct setting turns◆Preset methodSet 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 ofturns and calculate the number of overshot turns. Go into programming modeand subtract the number of the overshot turns from the 『TURNS』to obtainthe required setting.This method has a higher throughput, however, the resulting stopping location may not be precise.◆High-Low speed methodThis 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 reachingthe total number of turns. This can result in precise stopping location.◆Double-brake methodAs 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 atlow 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).6. WINDING EXECUTION6.1.
