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 2 motor
revolutions to 1 load revolution, set p9521 = 1, p9522 = 2, p2504 = 2 and p2505 = 1.
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)

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.
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)
