(2)Enabling/Disabling the Overtravel Signal
A parameter can be set to disable the overtravel signal. If the parameter is set, there is no need to wire the overtravel input
signal.
Parameter
Meaning
Pn000
b.□□0□
In the case of ProNet-
□□□
MG servo drives,the forward rotation prohibited(P-OT) signal
is input fromCN1-16(factory setting).
In the case of ProNet-
□□□
EG-EC servo drives, the forward rotation prohibited(P-OT)
signal is input fromCN1-17(factory setting).
b.□□1□
Disables the forward rotation prohibited (P-OT) signal. (Allows constant forward rotation.)
b.□0□□
In the case of ProNet-
□□□
MG servo drives,the reverse rotation prohibited(N-OT) signal
is input fromCN1-17(factory setting).
In the case of ProNet-
□□□
EG-EC servo drives,the reverse rotation prohibited(N-OT)
signal is input fromCN1-18 (factory setting).
b.□1□□
Disables the reverse rotation prohibited(N-OT) signal. (Allows constant reverse rotation.)
·
Applicable control modes: Speed control, position control, and torque control.
·
After changing these parameters, turn OFF the main circuit and control power supplies, and then turn them ON again to
enable the new settings.
·
A parameter can be used to re-allocate input connector number for the P-OT and N-OT signals. Refer to
3.2.2 I/O Signal
Names and Functions
.
(3) Selecting the Servomotor Stop Method
This is used to set the stop method when an overtravel(P-OT,N-OT)signal is input while theservomotor is operating.

H
.□□□0
Stop by dynamic
brake
Coast
Rapidlly stops the servomotor by dynamic braking(DB),
then places it into coast(power OFF) mode.
H
.□□□1
Coast to a stop
Stops the servomotor in the same way as when the
servo is OFF(coast to a stop ), then places it into
coast(power OFF) mode.
H
.□□□2
S-OFF
/Overtravel
Coast
Stops the servomotor by dynamic braking (DB) when
servo OFF, stops the servomotor by plug braking when
overtravel, and then places it into coast (power OFF)
mode.
H
.□□□3
Makes the servomotor coast to a stop state when servo
OFF, stops the servomotor by plug braking when
overtravel, and then places it into coast (power OFF)
mode.
H
.□□□4
Zero Clamp
Stops the servomotor by dynamic braking (DB) when
servo OFF, stops the servomotor by plug braking when
overtravel, and then places it into zero clamp mode.
H
.□□□5
Makes the servomotor coast to a stop state when servo
OFF, stops the servomotor by plug braking when
overtravel, then places it into zero clamp mode.
