12. WHEN USING WITH A GENERAL-PURPOSE INTERFACE

12.2.3 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-JE-_C Servo
Amplifier Instruction Manual". The symbols of the control mode in the table indicate the following:
CP: Positioning mode (point table method)
PS: Positioning mode (indexer method)
" " and " " of the table show the following.
: Usable device by default
: Usable device by setting the following parameters
[Pr. PD06], [Pr. PD09], [Pr. PD12], [Pr. PD15], [Pr. PD18], [Pr. PD24], and [Pr. PD27]

pin No.
CN3-1 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].
Setting
value of EM2/EM1
[Pr. PA04]
0 _ _ _ EM1
2 _ _ _ EM2
EM2 and EM1 are mutually exclusive.
(CN3-1) When using EM1, set [Pr. PA04] to "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).
CN3-2 Turn SON on to power on the base circuit, and make the servo amplifier
ready to operate. (Servo-on status)
Turn SON off to shut off the base circuit, and coast the servo motor.
Set [Pr. PD01 Input signal automatic on selection 1] to "_ _ _ 4" 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
"MELSERVO-JE Servo amplifier Instruction Manual (Troubleshooting)".
Turning RES on in an alarm-free status shuts off the base circuit. The base
circuit is not shut off when [Pr. PD35 Function selection D-1] is set to " _ _
1 _ ".
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.
