3.5 Signal (device) explanations
The pin numbers in the connector pin No. column are those in the initial status.
For the I/O interfaces (symbols in I/O division column in the table), refer to section 3.9.2. The symbols in the
control mode field of the table shows the followings.
P: Position control mode
S: Speed control mode
T: Torque control mode
" " and " " of the table shows the followings.
: Usable device by default.
: Usable device by setting the following parameters.
[Pr. PA04], [Pr. PD03] to [Pr. PD26], [Pr. PD28], and [Pr. PD47]

Forced stop 2
EM2
CN1-42
Turn off EM2 (open between commons) to decelerate the servo motor to a
stop with commands.
Turn EM2 on (short between commons) in the forced stop state to reset
that state.
The following shows the setting of [Pr. PA04].

EM2 and EM1 are mutually exclusive.
EM2 has the same function as EM1 in the torque control mode.
Forced stop 1
EM1
(CN1-42)
When using EM1, set [Pr. PA04] to "0 _ _ _" to enable EM1.
When EM1 is turned off (open between commons), the base circuit shuts
off, and the dynamic brake operates to decelerate the servo motor to a
stop.
Turn EM1 on (short between commons) in the forced stop state to reset
that state.
DI-1
Servo-on
SON
CN1-15
Turn SON on to power on the base circuit and make the driver ready to
operate. (servo-on status)
Turn it off to shut off the base circuit and coast the servo motor.
Set "_ _ _ 4" in [Pr. PD01] to switch this signal on (keep terminals
connected) automatically in the driver.
DI-1
Reset
RES
CN1-19
Turn on RES for more than 50 ms to reset the alarm.
Some alarms cannot be deactivated by RES (Reset). Refer to chapter 8.
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 [Pr. PD30].
This device is not designed to make a stop. Do not turn it on during
operation.
