Arrangement and Function of Control Circuit Terminal Block

The table below shows the arrangement of the control circuit terminal block, and description and spec-

ifications of each terminal.

Control Circuit Terminal Block

Terminal name

DC reactor connection terminal

Braking resistor connection termi-

Regenerative braking unit con-

nection terminal

Control power supply auxiliary in-

Ground terminal

Remove the short-circuit bar between the terminals

P1 and P(+), and connect an optional DC reactor.

Connect an optional braking resistor (if a braking

torque is required).

Connect optional regenerative braking units (if a

braking torque is required and that produced by the

built-in braking circuit is insufficient).

To hold a batch alarm signal when the protection

function is activated even if the main power supply

of the inverter is cut off or to display the Digital Op-

erator at all times, connect these terminals to the

power supply (at a capacity of 1.85 kW or more, for

details, refer to 2-3-4 Wiring for Main Circuit Termi-

nals on page 2-15).

This is the ground terminal. Connect this terminal to

200-V class should be connected under type-D

grounding conditions; 400-V class should be con-

nected under type-C grounding conditions.
