3.1.2 Setting the Overtravel Limit Function
1) The overtravel limit function forces the moving part of the machine to stop when it ex-
ceeds the movable range.
2) To use the overtravel limit function, connect the following input signal terminals correctly.
→ Input P-OT 1CN-42
Forward Rotation Prohibited
(Forward Overtravel)
For Speed/Torque
Control and
Position Control
→ Input N-OT 1CN-43
Reverse Rotation Prohibited
(Reverse Overtravel)
For Speed/Torque
Control and
Position Control
Inputs terminals for overtravel limit switch.
For linear motion, connect a limit switch to prevent
damage to the machine.
P-OT ON: 1CN-42 is
at low level.
Forward rotation allowed. Normal operation status.
OFF: 1CN-42
is at high level.
Forward rotation prohibited (reverse rotation allowed).
N-OT ON: 1CN-43 is
at low level.
Reverse rotation allowed. Normal operation status.
OFF: 1CN-43
is at high level.
Reverse rotation prohibited (forward rotation allowed).
