2.4 Signal (device) explanations

For the I/O interfaces (symbols in I/O division column in the table), refer to section 2.5.2.
The pin Nos. in the connector pin No. column are assigned by default.

Forced stop 2 EM2
Forced stop 1 EM1
POINT
In the pressure control mode, EM2 functions the same as EM1.
Connector
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 or
EM1
EM2 and EM1 are mutually exclusive.
In the pressure control mode, EM2 functions the same as EM1, and thus the
forced stop deceleration is not executed.
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.
(CN3-20)
The forced stop will be reset when EM1 is turned on (short between commons).
Set [Pr. PA04] to "0 1 _ _" to disable EM1.
Function and application
Deceleration method
EM2 or EM1 is off
MBR (Electromagnetic
brake interlock) turns off
EM1
without the forced stop
deceleration.
MBR (Electromagnetic
brake interlock) turns off
EM2
after the forced stop
deceleration.
