( 2 ) Parameter Settings

[ a ] Use/Not Use Overtravel Input Signals

The following parameters are used to enable and disable the overtravel input signals.

[ b ] Selecting Motor Stopping Methods for Overtravel

When using the overtravel function has been enabled, the following parameters are used to set the methods for stopping
the motor. Select the methods for stopping when the P-OT or N-OT is input during motor running.

Parameter

Name

Set Value

Item

Default

Cn-01
Bit 2

Use/Not Use P-OT Input
Signal

0

(Recommended)

Enables use of Positive Prohibit Input Signal
(P-OT). (Forward rotation prohibited when
open, allowed for 0 V.)

0

1

Disables use of Positive Prohibit Input Signal
(P-OT). (Forward rotation always allowed.)

Cn-01
Bit 3

Use/Not Use N-OT Input
Signal

0

(Recommended)

Enables use of Negative Prohibit Input Signal
(N-OT). (Reverse rotation prohibited when
open, allowed for 0 V.)

0

1

Disables use of Negative Prohibit Input Signal
(N-OT). (Reverse rotation always allowed.)

Default

Cn-01
Bit 8

Selection of stopping
method for overtravel

0

(Recommended)

Uses the same stopping method as for Servo
OFF.
Stops the motor according to Cn-01 bit 6 set-
ting (dynamic brake or coasting) when over-
travel is detected.

0

1

Decelerates the motor to a stop by applying the
torque specified in Cn-06 (EMGTRQ Emer-
gency Stop Torque) when overtravel is
detected.

Cn-01
Bit 9

Selection of processing
after stopping for over-
travel

0

(Recommended)

Decelerates the motor to a stop and then turns
OFF the Servo.

0

1

Decelerates the motor to a stop and then sets it
in the zero-clamp mode.

Cn-01
Bit 6

Selection of stopping
method for motor when
servo turns OFF

0

Stops the motor by applying dynamic brake
(DB).

0

1

Makes the motor coast to a stop.
Current is not supplied to the motor and the
machine stops due to friction.

Cn-01
Bit 7

Selection of processing
after stopping for over-
travel

0

Stops the motor by applying dynamic brake
(DB) and then releases the DB.

0

1

Stops the motor by applying dynamic brake
(DB) and then holds the DB.
