3)根据实际情况调整被偿参数值,(因为同步带弹性形变较大,所以改变方向时需加一定的补偿)。
4)适当地增大马达电流,提高驱动器电压(注意选配步进电机驱动器)选扭矩大一些的马达。
5)系统的干扰引起或驱动器的误动作,我们只能想办法找出干扰源,降低其干扰能力(如,加大间隔距离等),切断传播途径,提高自身的抗干扰能力,常见措施:①用双纹线代替普通导线,系统中信号线与大电流或大电压变化导线分开布线,降低电磁干扰能力。②用电源滤波器把来自电网的干扰波滤掉,在条件许可下各大用电设备的输入端加电源滤波器,降低系统内各设备之间的干扰。③设备之间用光电件进行信号传送,在条件许可下,脉冲和方向信号用差分方式加光电隔离进行信号传送。在感性负载(如电磁、电磁阀)两端加阻容吸收或快速泄放电路,感性负载在开头瞬间能产生10~100倍的尖峰电压,如果工作频率在20khz以上。
6)软件做一些容错处理,把干扰带来影响消除。

日本轴承企业注重制造技术和工艺的开发。在代表团所访问的厂家中,企业均是高度自动化的生产和在线自动检测。但在生产线上,并非所有的设备都是进的,有的还是2世纪6或7年代的设备,但能和生产线结合在一起,并且能够保证产品质量,这得益于日本企业普遍重视生产技术的开发。代表团考察的企业大部分是生产厂,但技术开发部门都有较强的开发能力,在重视新产品开发的同时,同样注重生产技术和工艺的开发和创新,从而确保产品的质量。

谨防不锈钢变不锈铁不少商家在宣传不锈钢五金配件产品时会用不锈铁代替,即在不锈钢材料中掺合了不少铁成分,价格相差将近两倍。以浴巾架为例,不锈钢材质的价格平均在每个2元,而不锈铁的价格只有每个7元,表面上两者基本相同,但不锈钢材料表面更光亮些,不锈铁使用时间一长,表面容易发黑生锈。此外,还有一些假冒产品使用劣质铝合金为原料,表面镀上一层金属亮光,冒充高档不锈钢,判断这两种材料,消费者可以敲打表面,如果发出清脆的声音则大多是不锈钢,如果是沉闷的声音,则很可能是披着外衣的铝合金。
