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].

0 0 _ _ EM1
2 0 _ _ EM2
Not using
0 1 _ _ EM2 or
EM1
Not using
2 1 _ _ EM2 or
EM1
EM2 and EM1 are mutually exclusive.
EM2 has the same function as EM1 in the torque mode.
(CN3-20) When using EM1, set [Pr. PA04] to "0 0 _ _" to enable EM1.
Turn EM1 off (open between commons) to bring the servo motor to a forced
stop state. The base circuit shuts off, and the dynamic brake is operated and
decelerates the servo motor to a stop.
Turn EM1 on (short between commons) in the forced stop state to reset that
state.
Set [Pr. PA04] to "0 1 _ _" to disable EM1.
CN3-10 The touch probe function is available to latch the current position by sensor
input. Turn it on to latch the current position. For the touch probe function, refer
CN3-1
to the MR-J4-_TM_ Servo Amplifier Instruction Manual for each communication
method.
