7-42
(5) Connecting Regenerative Resistors
Do not touch the regenerative resistors because they reach high temperatures. Use heat-resistant, non-flam-
mable wiring and make sure that the wiring does not touch the resistors.
Refer to 6.6 SERVOPACK Main
Circuit Wire Size for connecting wire size when connecting an external regenerative resistor.
(a) SERVOPACKs with Capacities of 400W or Less
(b) SERVOPACKs with Capacities of 0.5 to 5.0 kW
IMPORTANT
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 regen-
erative resistor between the B1 and B2 terminals.
The user must provide the regenerative resistor.
Note: Be sure to remove the lead wire between the
B2 and B3 terminals.
