[Example of calculation of reference value]
Moving range after OT × 0.7 = Homing speed × Reduction ratio × Ball screw lead
× (Homing speed/2000 [r/min] × Deceleration time after homing OT/1000/60) × 1/2
30[mm] ×0.7 = 1000.00 [r/min] × (1/5) × 20 [mm]
× (1000.00 [r/min]/2000 [r/min] × Deceleration time at OT during homing /1000/60) × 1/2
Deceleration time at OT during homing = 1260.0 [ms]
•
If 1 (stop) is selected with parameter PA2_24 (selection of operation at OT during homing), stoppage
occurs according to parameter PA2_60 (third torque limit). In this case, the homing motion is
stopped upon detection of OT.

These parameters are enabled if “5” (stopper) is selected for PA2_11 (home position shift amount
reference signal).
Enter these parameters to perform homing in applications such as positioning of a cylinder or the like
where the home position LS or +/-OT cannot be used.
Enter the stopper contact detection time and dead stop torque limit.

Deceleration time at homing OT
The acceleration time and
deceleration time are based on
2000 [r/min].
Acceleration time 1 or acceleration time 2
+OT and -OT are generally
normally closed contact signals.
