Safely referencing under EPOS
Basic positioning with safe referencing
Some safety functions (e.g. SLP, SP) require safe referencing. If EPOS is active at a drive,
when referencing using EPOS, then the absolute position is also automatically transferred to
the Safety Integrated functions.
The Safety Integrated functions only evaluate the absolute position if a safety function is
parameterized, which requires an absolute value, e.g. SLP.
The following are examples for a load-side position calculation, depending on various
encoder mounting versions and axis types.
Example 1:
Safety Integrated Extended functions monitor the rotating load. EPOS and Safety Integrated
Extended functions use the same rotary encoder at the motor. The rotating load is coupled to
the motor via a gear. The speed/position values of the spindle are calculated.
● p2506 = 360000 => a position of 360000LU (r2521) corresponds to 360° (r9708)
● p2506 = 10000 => a position of 10000LU (r2521) corresponds to 360° (r9708)
