9.4 Extended functions
The ratio for the gearbox used must be parameterized in p9521/p9522 for Safety Integrated
Extended Functions and in p2504/p2505 for EPOS.
For a gearbox to convert from 2 motor revolutions to 1 load revolutions, set:
● p9521 = 1
● p9522 = 2
● p2504 = 2
● p2505 = 1
Example 2:
Safety Integrated Extended Functions monitors the linear axis using the rotating motor
encoder.
EPOS references using the linear scale.
● p2503 = 100000 => a position of 100000LU (r2521) corresponds to 10 mm (r9708)
● p2503 = 10000 => a position of 10000LU (r2521) corresponds to 10 mm (r9708)
Figure 9-48
Safety Integrated Extended function uses the rotating motor encoder. The gearbox is
parameterized using p9521/p9522. The spindle pitch is parameterized in p9520. To calculate
the load-side absolute position, EPOS directly uses the load-side linear scale. In this
example, EPOS does not have to take into account the gearbox ratio and spindle pitch.
Example 3:
Safety Integrated Extended Functions monitor the linear axis using the rotating motor
encoder. EPOS referenced using the same rotary motor encoder.
● p2506 = 10000, p9520 = 5 mm/revolution => a position of 10000LU (r2521) corresponds
to 5 mm (r9708)
● p2506 = 5000, p9520 = 5 mm/revolution => a position of 10000LU (r2521) corresponds to
10 mm (r9708)
