Auto Mode - WAGO -I/O-SYSTEM 750 Manual

28 • 750-636 [DC Drive Controller]
Function Description
Example 2:
PU = BD
PD = 0
RT = 0
OZ = 0
OT = 0
Fig. 2.1.1-8: Example 2
The braking distance initializes the prestop. The motor turn-off position is
below the setpoint position. Due to the prestop, the stop position is exactly the
setpoint position.
Example 3:
PU = BD
PD = 0
RT = 0
OZ = 0
OT = 0
Fig. 2.1.1-9: Example 3
The short distance to the setpoint position (SP-IP) < (AD+BD) has made it
impossible to precisely reach the setpoint position, despite the prestop being
set correctly.
NOTICE:
The program prevents the acceleration phase in both the base and auto modes
from being stopped prematurely. This mainly affects a ramp drive.

For the following examples, it is presumed that the acceleration and the brake
path have the same distance.
