Control Of The Modes And The Skew Damping For The Hydraulic System - Siemens SIMOTION D4x5-2 DP/PN Operating Instructions Manual

TLS control function description

7.5 Control of the modes and the skew damping for the hydraulic system

End of a movement
At the end of the movement, the "motion_terminated_sKa" status bit is set. It can be used to
reset the "move_sKa" control bit, which deactivates the position controller.
Note
In the transition phase, the "motion_terminated_sKa" status bit may bounce. This can be
remedied by using a timer to evaluate the status bit in the higher-level control.
Reset the "move_sKa" control bit when the "motion_terminated_sKa" status bit is equal to 1 for
a defined time.
7.5 Control of the modes and the skew damping for the hydraulic system
The various TLS modes can be created with certain combinations of following control bits.
Table 7-3 Control of the TLS modes
mode_comm
Inch bit single cylinder (1)
move_zero
Inch bit TLS (2)
tls_pos (3)
skew_target_ext (3)
hold_trim_list (3)
* The value that the bit has is irrelevant for the mode.
Notes on the table:
(1) In this time, the value 1 means that one or more control bits are set in a_in_comm,
(2) In this time, the value 1 means that one of the control bits trim_right, trim_left, list_water,
(3) The variants stated here are described in Chapter TLS modes and TLS functions
Comment on controlling changes between "cylinder jogging" mode and the other TLS modes
These changes are performed via the control bit mode_comm according to the above table.
The following general condition applies:
During a value change to the control bit "mode_comm," the control bit "move" must not be set.

list_land, skew_right, skew_left is set. This means that it is possible to travel in one TLS
direction in TLS inch mode at any one time.
(Page 241).
A change to the status of hold_trim_list must be performed by setting tls_pos.
