When connected to
an HG-JR motor, the
CN2
encoder cable needs
to be changed.

CN6
When not using the
STO function, attach
the short-circuit
CN8
connector supplied
with the drive unit to
CN8 (STO I/O signal
connector).
The structure of the
TE1
main circuit terminal
block varies
TE2-1
depending on the
capacity. Refer to
TE3
"Part 6 Common
Reference Material".
