Connector pin No.
Details
RES+
CN10B - 1
If the restart function setting is enabled (parameter SF18: 1), this is
the terminal that is operated when the safety function status is
operational, and when performing recovery following an ecf alarm.
If the restart function is enabled, it will not be possible to restart
unless terminals [RES+] are turned ON→OFF→ON, even if the
status of the safety input terminal is recovered to ON after SS1, or
SLS and SBC activation.
The terminal [RES+] ON and OFF time must be 20 ms or longer.

RES-
CN10B - 9
This is the common terminal of [RES+].
SIA1+
CN10A – 4
If the terminal input turns OFF (open) with a redundant input signal,
the safety function set with parameter SF12 will run.
If either of the input terminals turns OFF (open), an ecf alarm will
be output, and the status will be STO. Ensure that the input time
difference between terminals [SIA1+] and [SIA2+] is 50 ms or less.
It is necessary to reboot the power supply to clear the alarm status.
SIA2+
CN10B – 4
SIA1-
CN10B - 12
This is the common terminal of [SIA1+].
SIA2-
CN10A - 12
This is the common terminal of [SIA2+].
SIB1+
CN10B - 5
If the terminal input turns OFF (open) with a redundant input signal,
the safety function set with parameter SF13 will run.
If either of the input terminals turns OFF (open), an ecf alarm will
be output, and the status will be STO. Ensure that the input time
difference between terminals [SIB1+] and [SIB2+] is 50 ms or less.
It is necessary to reboot the power supply to clear the alarm status.

PI_SSM1
CN10B – 6
This is the power supply input terminal for SSM signal output.
Electrical specifications: 24 VDC ±10%
PI_SSM2
CN10A – 6
SSM1
CN10B – 14
This is a redundant output signal. The operation is selected by
setting with parameter SF09, and the terminal turns OFF if the
parameter SF10 speed level is exceeded.

This is the power supply input terminal for SBC signal output.
Electrical specifications: 24 VDC ±10%
PISBC2
CN10A – 8
SBC1
CN10B – 16
This is the brake signal used to operate the redundant non-excitation
actuating brake. Select SBC function operation with parameter SF11.
The status between terminal [PI_SBC■] and terminal [SBC■] is OFF
(open) when the servomotor is running free with STO. Furthermore,
assign SBC feedback functions (parameters: SF12, SF13) to
terminal [SIA■] or terminal [SIB■], and connect brake operation relay
contact b to the terminal to which the function is assigned.
