3.3.2 Signal explanations

For the I/O interfaces (symbols in I/O column in the table), refer to Section 3.6.2.
In the control mode field of the table
P : Position control mode, S: Internal speed 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.

POINT
The acceptance delay time of each input signal is less than 10ms.
Connec-

No.
CN1-4 Connect SON-SG to switch on the base circuit and make the servo
amplifier ready to operate (servo-on).
Disconnect SON-SG 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.
CN1-3 Disconnect RES-SG for more than 50ms to reset the alarm.
Some alarms cannot be deactivated by the reset signal. (Refer to
Section 10.2.1.)
Shorting RES-SG in an alarm-free status shuts off the base
circuit. The base circuit is not shut off when " 1
parameter No. 51.
CN1-6 To start operation, short LSP-SG and/or LSN-SG. Open them 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.)
