3.5 Signal explanations

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: Speed control mode, T: 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. PD03 to PD08, PD10 to
PD12, PD13 to PD16, PD18.
The pin No.s in the connector pin No. column are those in the initial status.

CN1-15 Turn SON on to power on the base circuit and make the servo
amplifier ready to operate (servo-on).
Turn it off to shut off the base circuit and coast the servo motor.
Set " 4 " in parameter No. PD01 to switch this signal on
(keep terminals connected) automatically in the servo
amplifier.
CN1-19 Turn RES on for more than 50ms to reset the alarm.
Some alarms cannot be deactivated by the reset (RES). Refer to
section 9.1.
Turning RES on in an alarm-free status shuts off the base circuit.
The base circuit is not shut off when "
No. PD20.
This signal is not designed to make a stop. Do not turn it ON during
operation.
CN1-43 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 5.4.3.)

When LPS or LSN turns OFF, an external stroke limit warning (AL.
99) occurs, and Warning (WNG) turns OFF. However, when using
WNG, set the parameter No. PD13 to PD16/PD18 to make it usable.
