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 regenerative
capacity is insufficient.
Turns the servo
ON and OFF.
Install a surge
suppressor.

Suppression.
*1: The positive terminal for the main circuit is only available for use
in the three-phase (200 VAC, 7.5 kW) SERVOPACKs.
Do not use the positive terminals 1 or 2.
*2: Before connecting an external regenerative resistor to
the SERVOPACK, be sure to disconnect the lead between terminals
B2 and B3.
