Controlling Travel And Skew Damping With Electric Drive - Siemens SIMOTION D4x5-2 DP/PN Operating Instructions Manual

Otherwise, the error E77 occurs, which ignores the control bit "move".
That is in line with the information in Chapter TLS modes and TLS functions (Page 241). This
states that such a change must be performed when the cylinder is not moving.
Position limits in "TLS jogging" mode
In TLS jogging, it is not possible to move beyond the limits P256, P257 and P258. If the actual
position is outside these limits when such a movement is started, the system will only permit
movement toward the valid region. The other direction is blocked.
Skew damping
The skew damping can be selected in all TLS modes with the exception of "cylinder jogging"
mode via the "as_on" control bit

Controlling travel and skew damping with electric drive

When traveling with the electric drive, the process is not divided into different operating modes.
● skewpos_ext=0
In this case, when "mode_comm" is set, position-controlled travel is activated without
internal limitation of the axis via the input bits "ska_in_comm" and "ska_out_comm." The
input signal "rskewpos_set" of DCC block DCC_SCTLS2 has no significance in this case.
● skewpos_ext=1
In this case, the input signal "rskewpos_set" is switched directly to position control of the
skew axis by setting "mode_comm."
● mode_comm=0
This makes it possible after setting "move_ska" (see Chapter Controlling movement of the
electric drive (Page 259)) to hold the skew axis in position 0 by position control (as_on=0)
or to activate the skew damping function (as_on=1).
