Positioning mode
To allow the spindle to be positioned from the NC, its position has to be adjusted
using the measuring system. This operation is called "synchronization".
As a rule, synchronizing is done to the zero mark of the connected encoder or
to a BERO as zero mark substitute.
The machine data
S
Set MD 34100: REFP_SET_POS (reference point value).
defines the actual position of the spindle at the zero mark position.
The machine data
S
MD34090: REFP_MOVE_DIST_CORR (reference-point offset)
is used to enter the zero mark offset.
The machine data
S
MD 34200 ENC_REFP_MODE (referencing mode)
specifies which signal is used for synchronization:
1 = encoder zero mark
2 = BERO.
The drive SIMODRIVE 611 universal supports the connection of a BERO as a
zero mark substitute for synchronizing the spindle.
For the exact procedure of operating a BERO on SIMODRIVE 611 universal,
