Hello, when SSI encoder range is smaller as the mechanical range of the axis, you have to use positiontracking. Basic positioner of CU250S doesn't support position tracking. When you use Technology object, you have to set encoder to "cyclic absolute" in the settings of the TO. 3.7.2.2 Absolute actual value (S7-1500, S7-1500T) The actual value in the PROFIdrive telegram is based on an absolute value. After POWER ON, position zero is displayed. The first transition of the CPU to RUN mode starts the actual value update. The actual value is then also updated in CPU STOP mode. The supplied absolute value is assigned to the associated mechanical axis position by means of the absolute encoder adjustment. The absolute encoder adjustment must be performed once. The absolute value offset is retentively saved beyond the switching on/off of the controller. Differentiation of absolute values: • The measuring range of the encoder is larger than the traversing range of the axis: Absolute value with setting absolute • The measuring range of the encoder is smaller than the traversing range of the axis: Absolute value with setting cyclic absolute https://support.industry.siemens.com/cs/ww/en/view/109781849 |
