5.7 Connecting Regenerative Resistors
5-27
(5) Connecting Regenerative Resistors
(a) SERVOPACKs with Capacities of 400 W or Less
(b) SERVOPACKs with Capacities Larger than 400W
Do not touch the regenerative resistors because they reach high temperatures. Use heat-resistant, non-
flammable wiring and make sure that the wiring does not touch the resistors.
Refer to 4.1 SERVOPACK
Main Circuit Wire Size for connecting wire size when connecting an external regenerative resistor.
Connect an external regenerative resistor between
B1/
and B2 terminals.
Note: The user must provide the regenerative resis-
tor.
Disconnect the wiring between the SERVOPACK’s
B2 and B3 terminals and connect an external
regenerative resistor between the B1/
and B2
terminals.
The user must provide the regenerative resistor.
Note: Be sure to take out the lead wire between the
B2 and B3 terminals.
