8.8 Basic positioner
MDI mode with the use of PROFIdrive telegram 110.
If the 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 "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 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 rejected by 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 specification / MDI" modes.
