40-6 Revised March, 2012
40.3 _DMC_01_start_v3_rline_xy
FORMAT
I16 PASCAL _DMC_01_start_v3_rline_xy (U16 CardNo, U16* NodeID, U16* SlotID,
I32 pos1_x, I32 pos1_y, I32 pos2_x, I32 pos2_y, U16 mode, F64 param, I32 StrVel,
I32 ConstVel, I32 EndVel, F64 TPhase1, F64 TPhase2, U16 m_curve, U16 m_r_a)
Purpose
2-axis linear, arc interpolation motion control with added EndVel.
※Values of StrVel and EndVel can be greater than MaxVel.
