3.3.2 Signal explanations

For the I/O interfaces (symbols in I/O division column in the table), refer to Section 3.6.2.
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 among parameters 43 to

49.
The pin No.s in the connector pin No. column are those in the initial status.

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
(servo off).
Set " 1" in parameter No. 41 to switch this signal on
(keep terminals connected) automatically in the servo
amplifier.

Reset

RES

CN1B

14

Turn RES on for more than 50ms to reset the alarm.
Some alarms cannot be deactivated by the reset signal. Refer to
Section 10.2.
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. 51.

DI-1

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. 22 to make a slow stop.
(Refer to Section 5.2.3.)
