STOCOM
CN8-3
Common terminal for the STO1 and STO2 input signals
DI-1
STO1
CN8-4
Input the STO status of STO1.
STO state (base circuit shut-off): Open between STO1 and STOCOM.
STO release state (in driving): Close between STO1 and STOCOM.
Before turning off STO1, stop the servo motor in the servo-off state or with forced stop deceleration by turning
off EM2 (Forced stop 2).
DI-1
STO2
CN8-5
Input the STO status of STO2.
STO state (base circuit shut-off): Open between STO2 and STOCOM.
STO release state (in driving): Close between STO2 and STOCOM.
Before turning off STO2, stop the servo motor in the servo-off state or with forced stop deceleration by turning
off EM2 (Forced stop 2).
DI-1
TOFCOM
CN8-8
Common terminal for the TOFB1 and TOFB2 output signals
DO-1
TOFB1
CN8-6
