3.2 Resetting the origin 原点重新设置

The origin is set so that the robot can be used with a high accuracy. After purchasing the robot,always carry out this step before starting work. The origin must be reset if the combination of robot and controller being used is changed or if the motor is changed causing an encoder area. The origin setting methods and when each origin setting method required are shown in Table 3-2.

设定原点是为了能高精度地使用机器人而进行的操作。在机器人开始工作之前必须进行“原点设置”。在(使用之后),如果发生控制器与机器人的连接脱开、更换电机、编码器出现故障等情况,要进行“重新设置原点”。“重新设置原点”的方式类型和各设置方式的应用场合如表3-2所示。

表3-2 原点重新设置方式

Caution 注意:

• The origin is set using the jig method(No. 2)at factory default.

机器人出厂时,已通过校正棒方式(No. 2)进行了原点设定。

• The value set with the jig method is encoded and used as the origin data to be input at the initial startup after shipment. When the robot arm does not mechanically deviate(for example caused by replacement of the reduction gear,motor,or timing belt)or does not lose the encoder data,the origin data input method at shipment can be used to set the origin.

使用校正棒方式获得的数据被封装起来作为原点数据。在出厂后的初次使用时输入“原点数据”。当机器人本体没有发生机械拆分(如更换减速齿轮、电机、同步带)或丢失编码器数据,出厂设置的原点数据就可以用于设置“原点数据”。

• The origin data is inherent to the serial number of each robot arm.

每一序列号的机器人其原点数据是独有的。

• The ABS origin method is used to restore the previous data by aligning the triangular marks to each other for each axis to set the lost origin data.

ABS原点设置方式是使用各轴对准轴上的三角形标志的方法,重新恢复各轴原有的原点数据。

Caution 注意:

• The ABS origin method cannot be used when the robot arm mechanically deviates(for example caused by replacement of the reduction gear,motor,or timing belt).

在发生机器人本体的机械性拆分时(更换减速齿轮、电机、同步带)不能使用ABS原点设置方法。

• After the origin setting is completed,move the robot arm to the position where the ABS marks align each other,and check that the displayed joint coordinates of the position are correct.

原点设定完成后,务必将机器人本体移动至各轴ABS标记位置,并在显示屏上确认该位置的关节坐标是否显示正确。
