Remedy
• Calculate the distance of travel according to the speed
limit, zero point return speed and deceleration speed,
and determine the movement amount after activation at
the near-point dog so that the distance of travel is larger
than the deceleration distance.
• Set a smaller zero point return speed.
• Adjust the near-point dog position so that the movement
amount after activation at the near-point dog becomes
longer. (Refer to sections 8.2.7 and 8.2.8)
Execute mechanical zero point return (positioning start No.
9001). (Refer to section 8.2)
Correct the creep speed to within the zero point return
speed. (Refer to section 5.2.5)
Execute mechanical zero point return (positioning start No.
9001). (Refer to section 8.2)
Correct the JOG speed to within the setting range. (Refer
to section 11.2)
