these must be transferred before the control bit is set. Calculation of the travel curve is then
started. The direction signals, and thus the signals for opening the brake, are set when the
calculation has completed.
Section 3
The brake is opened. The output velocities are output for both drives.
End of travel
Travel in SAM mode is complete when the POS_COMPLETED status bit is set.
The following conditions must be fulfilled for this purpose:
● The difference between the current and target positions is less than the value in P162.
● The SC_COMPLETED status bit is set. This is achieved for pendulum deflections less than
P169.
The following signal sequence is performed:
Figure 6-9
Section 1:
Sway-controlled travel to the target position
Section 2:
Actual position approaches target position; the output velocity decreases.
Section 3:
Target position is reached, output velocity is less than the zero speed detection in P3. The
POS_COMPLETED status bit is set as a result.
Section 4:
The TRAVEL control bit must be reset. The direction signals are reset as a result. The brake
must be closed.
Section 5:
The brake has been closed (the BRAKE_CLOSED control bit has been set).
