DATA USED FOR POSITIONING CONTROL
Creep speed
Pr.14
[Setting contents]
• Set the creep speed (low speed immediately before stop after deceleration from
OPR speed).
• The creep speed has influence to detection tolerance in OPR method with near-
point dog method, and has influence to the size of impact at collision in OPR
method with the stopper 3.
[Precautions]
• Set "Creep speed" to equal to or less than "
speed" is exceeded, "Out of creep speed setting range" error (error code: 914)
occurs.

If setting a value that does not satisfy the condition, the value is dropped so that it
can be multiples of 25. Note if setting a value under 25, corresponding to pulse
unit, "Out of creep speed setting range" error (error code: 914) occurs.
