OPR. 5
Creep speed
Set the creep speed after near-point dog ON (the low speed just before stopping
after decelerating from the OPR speed).
The creep speed is set within the following range.
(
OPR. 4
OPR speed ) ≥ (
OPR. 5
Creep speed) ≥ (
Pr. 6
Bias speed at start)
Note) • The creep speed is related to the detection error when using the OPR
method with zero signal, and the size of the collision if a collision occurs
during OPR using the stopper.
• Set the "creep speed" to a value not more than "
OPR. 4
OPR speed". If
the "OPR speed" is exceeded, "the "Setting range outside creep speed"
error (error code: 914) will occur.
• Set the "creep speed" to a value not less than "
Pr. 6
Bias speed at start".
If it is less than the "bias speed at start", the "Setting range outside creep
speed" error (error code: 914) will occur.
