CHAPTER 4 PARAMETER
Automatic Operation Setting Parameter 4-69
4
(7) Homing pattern using the encoder Z-phase as a referenece signal for homing
When it is a machine which cannot install sensors, such as LS, PA2_12: Reference signal for
homing set as "Encoder Z-Phase".

07 Creep speed for homing 50.00 [r/min] 50.00 Always
08 Starting direction for homing 0: Forward rotation 0 Power
11 Reference signal for shift operation 1: Encoder Z-Phase 1 Power
12 Reference signal for homing 3: Encoder Z-Phase 0 Power
14 Home position shift unit amount 1000 [units] 1000 Always
Timing chart
(1) When ORG signal is ON, the motor rotates with Creep speed for homing according to
Starting direction for homing.
(2) If first encoder Z-Phase is detected, it moves by PA2_14: Homeing position shift unit
amount.
If PA2_12 is 3: Encoder Z-Phase, Reference signal for shift operation is always Encoder
Z-Phaze even if PA2_11 is set as which value.
When ±OT is detected at the start of homing, the motor does not rotate eve if PA2_24 is set as
which value. And ±OT is detected during the homing operation, the motor is stopped.
