Use for connecting to the linear servomotor.
Use for connecting the power supply ground terminal and linear
servomotor ground terminal.
1 and 2 is short-circuited with a jumper at the factory.
If the regenerative capacity is insuf-
ficient, connect an external regener-
ative resistor (option) between B1/
and B2.
If the regenerative capacity is insuf-
ficient, remove the wire or short bar
that shorts the connection between
B2 and B3, and connect an external
regenerative resistor (option)
between B1/
