2.3 Signal (device) explanations

The pin numbers in the connector pin No. column are those in the initial status.
For the I/O interfaces (symbols in I/O division column in the table), refer to section 3.9.2 of "MR-J4-_A_(-RJ)
Servo Amplifier Instruction Manual". The symbols in the control mode field of the table show the followings.
CP: Positioning mode (point table method)
BCD: Positioning mode (point table method in the BCD input positioning operation)
This method is available only when the MR-D01 unit is connected. Refer to chapter 12 for details.
CL: Positioning mode (program method)
PS: Positioning mode (indexer method)
" " and " " of the table show the followings.
: Usable device by default.
: Usable device by setting the following parameters.
[Pr. PD04], [Pr. PD06], [Pr. PD08], [Pr. PD10], [Pr. PD12], [Pr. PD14], [Pr. PD18], [Pr. PD20], [Pr. PD22] to
[Pr. PD26], [Pr. PD28], [Pr. PD44], [Pr. PD46], and [Pr. PD47]

Forced stop 2 EM2 CN1-42
Forced stop 1 EM1 (CN1-42) When using EM1, set [Pr. PA04] to "0 _ _ _" to enable EM1.
Servo-on SON CN1-15

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.
The following shows the setting of [Pr. PA04].
[Pr. PA04]
EM2/EM1
setting
0 _ _ _ EM1
2 _ _ _ EM2
EM2 and EM1 are mutually exclusive.
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.
Turn EM1 on (short between commons) in the forced stop state to reset
that state.
Turn SON on to power on the base circuit and make the servo amplifier
ready to operate. (servo-on status)
Turn it off to shut off the base circuit and coast the servo motor.
Set "_ _ _ 4" in [Pr. PD01] to switch this signal on (keep terminals
connected) automatically in the servo amplifier.
Turn on RES for more than 50 ms to reset the alarm.
Some alarms cannot be deactivated by RES (Reset). Refer to chapter 8.
Turning RES on in an alarm-free status shuts off the base circuit. The base
circuit is not shut off when " _ _ 1 _ " is set in [Pr. PD30].
This device is not designed to make a stop. Do not turn it on during
operation.

Function and application
Deceleration method
EM2 or EM1 is off
MBR (Electromagnetic MBR (Electromagnetic
brake interlock) turns brake interlock) turns
off without the forced off without the forced
stop deceleration. stop deceleration.
MBR (Electromagnetic MBR (Electromagnetic
brake interlock) turns brake interlock) turns
off after the forced off after the forced
stop deceleration. stop deceleration.
