B1

Braking resistor connection

-

To connect a braking resistor or braking resistor unit.

B2

+2

  • DC power supply input (+1 and -)

  • DC reactor connection (+1 and +2)

-

To connect peripheral devices, for example:

  • DC power input

  • Braking Unit

  • DC reactor

    Note:

    Remove the jumper between terminals +1 and +2 to connect a DC reactor.

+1

DC power supply input (+1 and -)

  • DC power supply input (+1 and -)

  • Braking unit connection (+3 and -)

-

+3

-

  • 200 V: D class grounding (ground to 100 Ω or less)

  • 400 V: C class grounding (ground to 10 Ω or less)

To ground the drive.
Note:

Use terminals - and B1 to connect a CDBR-type control unit to drive models 2004 to 2138 and 4002 to 4168 that have built-in braking transistors.
