Note
Continuous acceptance
Continuous acceptance (p2649 = 1) can only be set with a free telegram configuration
(p0922 = 999). No relative positioning is allowed with continuous acceptance.
The direction of positioning can be specified using p2651 (positive direction specification)
and p2652 (negative direction specification). If both inputs have the same status, the
shortest distance is traveled during absolute positioning (p2648 = "1") of modulo axes
(p2577 = "1").
To use the positioning function, the drive must be in the "Operation" state (r0002 = 0).
The following options are available for starting positioning:
●
p2649 is "1" and positive edge on p2647
●
p2649 is "0" and p2647 is "1"
–
positive edge on p2650 or
–
positive edge on p2649
An overview of the setpoint acceptance/direct setpoint input is show in function block
diagram 3620.
MDI mode with the use of PROFIdrive telegram 110.
If connector input p2654 is preset with a value
≠
0 (e.g. for PROFIdrive telegram 110 with
r2059[11]), then it will internally supply the control signals "Select positioning type", "Positive
direction selection" and "Negative direction selection". The following characteristics are
evaluated from the value of the connector input:
●
xx0x = absolute -> p2648
●
xx1x = relative -> p2648
●
xx2x = ABS_POS -> p2648, p2651
●
xx3x = ABS_NEG -> p2648, p2652
Intermediate stop and reject traversing task
The intermediate stop is activated using a 0 signal at p2640. After activation, the system
brakes with the parameterized deceleration value (p2620 or p2645).
The current traversing task can be rejected using a 0 signal at p2641. After activation, the
system brakes with the maximum deceleration (p2573).
The "intermediate stop" and "reject traversing task" functions are only effective in "traversing
blocks" and "direct setpoint input/MDI" modes.
