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: 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.

Ready signal input terminal.
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.

Alarm reset signal input terminal.
Disconnect RES-SG for more than 50ms to reset the alarm.
Some alarms cannot be deactivated by the reset signal. Refer to
Section 9.2.
The base circuit is shut off while RES-SG are shorted.
DI-1
{ { {
Forward/reverse rotation stroke end signal input terminals.
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.
