3.5 Signal (device) explanations

For the I/O interfaces (symbols in I/O division column in the table), refer to section 3.8.
The pin numbers in the connector pin No. column are those in the initial status.

pin No.
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].

Not using
2 1 _ _ EM2 and
EM1
EM2 and EM1 are mutually exclusive.
EM2 has the same device 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,
and the dynamic brake operates to decelerate the servo motor to a stop.
(CN3-10)
The forced stop will be reset when EM1 is turned on (short between commons).
Set [Pr. PA04] to "0 1 _ _" to disable EM1.
Devices can be assigned for these devices with controller setting. For devices
CN3-7
that can be assigned, refer to the controller instruction manual. You can assign
CN3-8
the following devices with MR-J4 series compatible controllers (R_MTCPU,
Q17_DSCPU, RD77MS_, and QD77MS_)
CN3-9
DI1-A: FLS for A-axis (Upper stroke limit)
CN3-20
DI2-A: RLS for A-axis (Lower stroke limit)
DI3-A: DOG for A-axis (Proximity dog)
CN3-21
DI1-B: FLS for B-axis (Upper stroke limit)
CN3-22
DI2-B: RLS for B-axis (Lower stroke limit)
DI3-B: DOG for B-axis (Proximity dog)
CN3-1
DI1-C: FLS for C-axis (Upper stroke limit)
CN3-2
DI2-C: RLS for C-axis (Lower stroke limit)
CN3-15
DI3-C: DOG for C-axis (Proximity dog)
