5 脚踏板灵敏度调整 adjustment of pedal sensitivity
1) 脚踏板动作由初始位置①(75 号参数)开始,缓慢向前踩至②(72+75 号参数)开始低速缝纫,
继续前踩至③(75+73 号参数)开始加速,再深踩至④(74 号参数)达到最高速度。 ②③段之间维持
起缝速度,③④段之间为无级调速过程;
Press the pedal from initial position ①( P75)and to ②( P72+75)slowly and start to low speed sewing, and
press ③(P75+73)continuously to accelerate and then to ④(P74)thus can get maximum speed. It maintains
starting speed between ②③, and ③④ is for speed adjustment duration.
2) 当脚踏板由初始位置①(75 号参数)开始,缓慢后踩至⑥(24 号参数)时自动完成回到上停针
动作;
The machine will finish up position action when the pedal starts from ①(P75)to ⑥(P24)slowly
3) 各参数数值设置需保证(24 号参数)<(75 号参数)<(75+72 号参数)<(75+73 号参数)<(74
号参数);
Make sure the value should be like this(P24)<(P75)<(P75+72)<(P75+73)<(P74);
4) 可通过监控模式下 025、026、028 号参数实时监测踏板模拟量最大值、踏板回中电压采样值、
踏板倒踩电压采样值,操作方式同上停针位置设置方式,不同位置下的踏板采样数值作为各参数的参
考值。如前踩很大距离机器还没有运转,可适当减小 72 参数(72+75 号参数应大于回中位置参数 75),
即可提高前踩的灵敏度;若机器过于灵敏,轻触踏板机器就开始运行,可适当加大 72 参数;若不容易
补针,稍微前踩,速度就迅速提高造成前冲多针,可适当增大 73 参数或减小 72 参数(即增大脚踏板
低速范围),也可以适当降低初始起缝速度(00 号参数)。
We can use P025、P026、P028 to check timely maximum monitoring value, voltage sample value when
the pedal is in half back position, voltage sample value when the pedal is back under monitoring mode.
Operation is the same as setting up needle position, and sample value can be a referenced value in
different place. If we press the pedal for a long distance but the machine does not work, then we can
decrease value of P72(P72+75>P75)which can improve sensitivity. In contrary, we can increase P72
value. If its not easy to add stitch and when we slightly press front, then the speed up sharply, we can
increase P73 or decrease P72 or lower the starting speed(P00)
