Siemens SINAMICS G120 - Traversing Blocks

6.8 Traversing blocks
Description
A traversing block describes a positioning instruction for the drive.
The converter saves 16 di󹪜erent traversing blocks, which it normally executes one after the
other. However, you can also directly select a speci󹪝c traversing block or skip traversing blocks.

Element Meaning
Number With this number in the range 0 to 15, every traversing block can be selected using
binary-coded control signals.
Job Positioning command: You can give the converter various commands. For some
jobs, you must also specify a parameter. See the table below.
Parameter
Mode Positioning mode: Positioning relative to the start position or absolute to the ma‐
chine zero point.

Job and parameters
Table 6-2 Job and parameters
Job Parameter Meaning
Positioning ---
• Axis absolute or relative positioning.
• Rotary axis with modulo correction in a positive or
negative direction, absolute positioning.
Travel to 󹪝xed stop Force [N] or torque
[0.01 Nm]
Traverse axis to a 󹪝xed stop:
• Linear axis with reduced force.
• Rotary axis with reduced torque.
Travel to 󹪝xed stop (Page 81)
Endless travel --- Traverse the axis at the speci󹪝ed velocity to the positive
or negative end of the traversing range.
Wait Time [ms] Wait the speci󹪝ed time.
Go to Number The converter then executes the next traversing block
with the speci󹪝ed number.
