3.5 Signal (device) explanations

For the I/O interfaces (symbols in I/O division column in the table), refer to section 3.8.2.
The pin numbers in the connector pin number column are those in the initial status.
3.5.1 Input device
(1) Input device pin
The following shows the input device pins and parameters for setting devices.
(2) Input device explanations
Device Symbol
Forced stop 2 EM2
Forced stop 1 EM1
Connector pin No.
CN3-2 (Note)
CN3-12 (Note)
CN3-19 (Note)
Note. When using external input signals (FLS, RLS, and DOG) of the servo amplifier with a
controller, assign devices to CN3-2, CN3-12, and CN3-19 pins. The CN3-2, CN3-12,
and CN3-19 pins are available with servo amplifiers having software version C5 or
later, and manufactured in May 2016 or later. For the servo amplifiers manufactured
in China, these pins have been available from the June 2016 production.

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.
Set [Pr. PA04] to "2 1 _ _" to disable EM2.
The following shows the setting of [Pr. PA04].

0 1 _ _ EM2 and
EM1
Not using
2 1 _ _ EM2 and
EM1
EM2 and EM1 are mutually exclusive.
Note that EM2 has the same function as EM1 in the torque control mode.
When using EM1, set [Pr. PA04] to "0 0 _ _" to enable EM1.
When EM1 is turned off (open between commons), the base circuit shuts off,
(CN3-20) 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).
Set [Pr. PA04] to "0 1 _ _" to disable EM1.
