Delay reading of actual position after field bus start (P-AXIS-00567)
P-AXIS-00567 | Delay reading of actual position after field bus start | |
Description | As soon as the drive field bus delivers cyclic values after start-up, the control is reading the actual position, delivered by the drive. During the transition into the cyclic processing it is assumed, that the drive controller already delivers a valid actual position. But for some drives this can not be ensured and during start-up this can cause position lag errors or invalid initialized axis positions. This parameter enables the delayed reading of the actual position for a definable number of bus cycles after field bus start. The exact parameter value has to be determined by "try and error". | |
