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 No. column are those in the initial status.

EM2
CN3-20
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].

EM2 and EM1 are mutually exclusive.
EM2 has the same function as EM1 in the torque mode.
Forced stop 1
EM1
(CN3-20)
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,
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.
