The following state diagram presents the homing sequence.
1) The direction depends on the selected homing mode (par. 62.01 HOMING METHOD). The speed is
defined by par. 62.07 HOMING SPEEDREF1.
2) Depends on the selected homing mode (par. 62.01 HOMING METHOD).
3) The speed is defined by par. 62.08 HOMING SPEEDREF2.
Source for the homing start signal is selected by par. 62.03 HOMING START.
Source for the latch signal (i.e. home switch) is selected by par. 62.04 HOME SWITCH TRIG.
Source for the positive limit switch is selected by par. 62.06 POS LIMIT SWITCH.
Source for the negative limit switch is selected by par. 62.05 NEG LIMIT SWITCH.
