3.5 Signal (device) explanations
For the I/O interfaces (symbols in I/O division column in the table), refer to section 3.9.2. In the control mode
field of the table
P: position control mode, S: speed control mode, T: torque control mode Torque control mode
: devices used with initial setting status, : devices used by setting [Pr. PA04] and [Pr. PD03] to [Pr.
PD28]
The pin numbers in the connector pin No. column are those in the initial status.

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
MBR (Electromagnetic
brake interlock) turns
off after the forced
stop deceleration.
MBR (Electromagnetic
brake interlock) turns
off after the forced
stop deceleration.
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.
The forced stop will be reset when EM1 is turned on (short between
commons).
DI-1
Servo-on
SON
CN1-15 Turn SON on to power on the base circuit and make the servo amplifier
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 servo amplifier.
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 section 8.1.
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.
