(2) Restrictions
A pulse generator with a zero signal is required. When using a pulse generator without a zero signal, generate a
zero signal using an external signal.
(3) Precautions during operation
• An error "Count method movement amount fault (error code: 206)" will occur and the operation will not start
if the "[Pr.50] Setting for the movement amount after near-point dog ON" is smaller than the deceleration
distance from the "[Pr.46] OPR speed" to "[Pr.47] Creep speed".
• If the speed is changed to a speed faster than "[Pr.46] OPR speed" by the speed change function (refer to

Page 543, Section 12.5.1.) during a machine OPR, the distance to decelerate to "[Pr.47] Creep speed"
may not be ensured, depending on the setting value of "[Pr.50] Setting for the movement amount after near-
point dog ON". In this case, the error "Count method movement amount fault" (error code: 206) occurs and
the Machine OPR is stopped.
• The following shows the operation when a machine OPR is started while the near-point dog is ON.
