MDI mode with the use of PROFIdrive telegram 110.
If connector input p2654 is preset with a connector input ≠ 0 (e.g. with PROFIdrive telegram
110 with r2059[11]), then it will internally manage the control signals "Positioning type
selection", "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 canceling traversing block
The intermediate stop is activated by a 0 signal at p2640. After activation, the system brakes
with the parameterized deceleration value (p2620 or p2645).
The current traversing task can be canceled by a 0 signal at p2641. After activation, the
system brakes with the maximum deceleration (p2573).
The "intermediate stop" and "cancel traversing task" functions are only effective in the
modes "traversing blocks" and "direct setpoint input/MDI".
