Protects the power
supply line by shutting
the circuit OFF when
an overcurrent is
detected.
Eliminates external
noise from the power
line.
Connect an external
regenerative resistor
to terminals B1 and B2
if the rgenerative capacity
is insufficient.
Turns the servo
ON and OFF.
Install a surge
suppressor.
