Description
I/O
division
STOCOM
CN8-3
Common terminal for input signal of STO1 and STO2
DI-1
STO1
CN8-4
Inputs STO state 1.
STO state (base shut-off): Open between STO1 and STOCOM.
STO release state (in driving): Close between STO1 and STOCOM.
Be sure to turn off STO1 after the servo motor stops by the servo-off state or with forced
stop deceleration by turning off EM2 (Forced stop 2).
DI-1
STO2
CN8-5
Inputs STO state 2.
STO state (base shut-off): Open between STO2 and STOCOM.
STO release state (in driving): Close between STO2 and STOCOM.
Be sure to turn off STO2 after the servo motor stops by the servo-off state or with forced
stop deceleration by turning off EM2 (Forced stop 2).
DI-1
TOFCOM
CN8-8
Common terminal for monitor output signal in STO state
DO-1
TOFB1
CN8-6
Monitor output signal in STO1 state
STO state (base shut-off): Between TOFB1 and TOFCOM is closed.
STO release state (in driving): Between TOFB1 and TOFCOM is opened.
DO-1
TOFB2
CN8-7
Monitor output signal in STO2 state
STO state (base shut-off): Between TOFB2 and TOFCOM is closed.
STO release state (in driving): Between TOFB2 and TOFCOM is opened.
DO-1
(2) Signals and STO state
The following table shows the TOFB and STO states when the power is on in normal state and STO1
and STO2 are on (closed) or off (opened).

(3) Test pulse of STO input signal
Set the test pulse off time inputted from outside to 1 ms or less.
13.2.3 How to pull out the STO cable
The following shows how to pull out the STO cable from the CN8 connector of the servo amplifier.
1)
2)
While pressing knob 1) of the STO cable plug in the
direction of the arrow, pull out the plug 2).
