22
Detection time for
contact-stopper
0 to 10000 [ms] 0 Always
23
Torque limit for
contact-stopper
0 to 100 [%] 0 Always
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 detection time and the torque limit on contact with the stopper.
For details, refer to “(7) Homing Pattern Using the Stopper” on page 4-67.
PA2_24 Selection of operation at OT detection during homing
No. Name Setting range
Default
value
Change
24
Selection of operation at
OT during homing 0: Reverse rotation
1: Stop and cancel the homing
0 Power
Specify the motion taken upon first OT detection during homing motion.
Specify 0 to reverse the motion upon first OT detection.
Specify 1 to cancel homing and stop upon detection of OT.
 Parameters related to homing
PA1_12 (Z-phase position offset)
No. Name Setting range
Default
value
Change
12 Z-phase position offset 0 to 1048575 [pulses]: 20 bits 0 Power
The encoder Z-phase position can be adjusted.
The Z-phase output position shifts by the pulse amount (pulse units) specified in the CCW
direction.
If the encoder Z-phase is selected as a reference signal for shift operation, adjust the encoder
Z-phase position with this parameter after motor replacement so that homing can be made to the
original position without changing the reference signal for homing (deceleration starting signal) or
homing parameters.
For details, refer to "PA1_12 Z-phase position offset" on page 4-14.
