Under one of the following conditions, the converter skips the 󹪝rst step and starts with step 2:
• The axis is already at the reference cam.
• There is no reference cam available.
Step 2: Travel to zero mark
The behavior of the axis in step 2 depends on whether a reference cam is available:
• Reference cam available: When the converter reaches the reference cam, the
axis accelerates in the opposite direction to the start
direction, to the "approach velocity zero mark".
• No reference cam is available: The converter accelerates the axis in the start direc‐
tion to the "approach velocity zero mark".
