SIMOVERT MASTERDRIVES Compendium Motion Control 7-23
Case 1: A rotary axis (U858.1 <> 0) is positioned absolutely
(POS_TYP = 0).
In this case, in addition to the mode, the direction of movement must be
determined through the two control binector inputs D_FWD or D_BWD:
[D_FWD] [D_BWD]
0 0 = shortest path
1 0 = always positive direction
0 1 = always negative direction
1 1
= no selection of direction of movement
(or: axis is stopped on ramp)
Case 2: The homing mode is selected with a circular or linear axis.
In this case, in addition to the mode, the direction of movement must be
determined through the two control binector inputs D_FWD or D_BWD:
[D_FWD] [D_BWD]
0 0
= no selection of direction of movement
(or: axis is stopped on ramp)
1 0 = positive direction
0 1 = negative direction
1 1
= no selection of direction of movement
(or: axis is stopped on ramp)
Case 3: A linear axis (U858.1 <> 0) is positioned absolutely
(POS_TYP = 0) or relatively (POS_TYP = 1).
In the case of relative positioning, the sign of the position setpoint
determines the direction of movement. With absolute positioning, the
direction of movement is determined by the difference between the
position setpoint and actual values. Activation of the control binector
inputs D_FWD or D_BWD has no effect.
Special case when
selecting direction
D_FWD and D_BWD
