AC servo systems
Note: * A regeneration resistor can be connected across the B1 and B2 terminals with 400 W and 750 W servo drives.
When using an external regeneration resistor with a 400 W servo drive, just connect it across the B1 and B2 terminals.
When using an external regeneration resistor with a 750 W servo drive, remove the jumper bar from the B2 and B3 terminals and then
connect the regeneration resistor across the B1 and B2 terminals.
