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.

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 control mode.
(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.
CN3-2
Devices can be assigned for these signals with controller setting. For devices
that can be assigned, refer to the controller instruction manual. The following
CN3-12
devices can be assigned for MR-J4 compatible controller (R_MTCPU,
CN3-19
Q17_DSCPU, RD77MS_ and QD77MS_).
