Ecat_Slave_Csp_Scurve_Rate - Delta EtherCAT Programming Manual

Cyclic Synchronous Position Mode (CSP)

9.20 _ECAT_Slave_CSP_Scurve_Rate


Syntax
9 U16 PASCAL _ECAT_Slave_CSP_Scurve_Rate (U16 CardNo , U16 AxisNo ,
U16 SlotNo , U16 Ratio)

Purpose
This is for setting the ratio of T-curve and S-curve during acceleration and deceleration.
Note:
1. Once this function is enabled, it will change the S-curve ratio of CSP motion command. However, the
setting of linear acceleration (T-curve) remains the same.
2. Like the function of _ECAT_Slave_CSP_Feedrate_Overwrite, multi-axis motion with continuous speed
can be achieved only when the first axis in the array is identical to the axis set in this API.
