3.5 Signal explanations
POINT
For the positioning mode, refer to section 13.2.3.
For the I/O interfaces (symbols in I/O division column in the table), refer to section 3.8.2.
In the control mode field of the table
P : Position control mode, S: Internal speed control mode, T: Internal torque control mode
: Denotes that the signal may be used in the initial setting status.
: Denotes that the signal may be used by setting the corresponding parameter No. PD02 to PD18.
The pin numbers in the connector pin No. column are those in the initial status.

P S T
Servo-on SON CN1-4 When SON is turned on, the power is supplied to the base circuit and the
servo amplifier is ready to operate (servo-on).
When SON is turned off, the power to the base circuit is shut off and the
servo motor coasts.
Set parameter No. PD01 to "
4 " to switch this signal on
(keep terminals connected) automatically in the servo amplifier.
DI-1
Reset RES CN1-3 When RES is turned on for 50ms or longer, an alarm can be reset.
Some alarms cannot be deactivated by the reset (RES). Refer to section
8.1.
Turning RES on in an alarm-free status shuts off the base circuit. The
base circuit is not shut off when "
1 " is set in parameter No. PD20.
This device is not designed to make a stop. Do not turn it ON during
operation.

LSP CN1-6 To start operation, turn LSP/LSN on. Turn it off to bring the motor to a
sudden stop and make it servo-locked.
Set "
1 " in parameter No. PD20 to make a slow stop.
(Refer to section 4.4.2.)

LSN CN1-7 Note. 0: off

When LSP or LSN turns OFF, stroke limit warning (99.
) occurs, and
warning (WNG) turns ON. However, when using WNG, set parameter
No. PD15 to PD18 to make it usable.
In the internal speed control mode, LSP and LSN turns ON automatically
if they are not assigned to the external input signals.
