[Pr.47] Creep speed
Once the near-point dog turns on, the control decelerates from OPR speed and stops. Set the speed of right before the stop,
which is a creep speed. Set the creep speed within the following range.
• ([Pr.46] OPR speed) ≥ ([Pr.47] Creep speed) ≥ ([Pr.7] Bias speed at start)
The creep speed is related to the detection error in the OPR method using the zero signal, and to the size of the shock when
a collision occurs in the OPR method using the stopper method.

■Buffer memory address
The following table shows the buffer memory address of this area.

[Pr.47] Creep speed
■Setting range
The setting range depends on the setting of [Pr.1] Unit setting.
Setting of [Pr.1] Unit setting
0: mm
1: inch
2: degree
3: pulse
*1 When this buffer memory area is set with programs, a calculation is performed in the positioning module to convert a setting value to the
value in each unit. For setting this buffer memory area, take the value after the unit conversion into consideration.
■Default value
The default value is 1 for all the axes.
