Fig. 73: Timing of the SHOM funcon
The homing process is for example started via the IRS signal (source can be set in
0x2880:001).
The safely limited speed (SLS) is always acvated. 4Sa
fely-Limited Speed (SLS) ^ 410.
Within a me period dened in 0x2882:002 (meout), the 0x2881:001 reference signal is
expected via the input X82/IRL (SHOM-Load). The reference signal denes the safe reference
point 0x2882:001 (home posion) in the absolute area.
When the reference point has been dened, homing is completed. A changeover to normal
operaon will follow.
