Start-up manual

COMPAX-M / -S

The final stage is enabled using a bridge between X3/1 - X3/1.

If this connection is missing, the final stage is voltage-free and error message E40

appears (see from Page 223).

! Energy recuperated during braking is stored in the supply capacitors. The

capacity and storable energy is:

COMPAX 45XXS: 330µF/52 Ws

COMPAX 85XXS: 500µF/80 Ws

If the recuperated energy causes overvoltage, then the internal ballast resistance is

engaged.

Enable internal ballast resistance: X2/5 - X2/6

The internal ballast resistance is enabled by a bridge between X2/5 and X2/6.

If this connection is missing, the controller operates without ballast resistance; in

braking mode, error message E38 may appear (see from Page 223).

We provide external ballast resistances for COMPAX 45XXS / 85XXS (see

Page 193).

Connecting a ballast resistance to COMPAX 4500S/ COMPAX 8500S

The ballast resistance is connected to HV, T

and PE.

The output is protected from short circuits.

Note!

When an external ballast resistance is connected, the bridge between R

and T

must be removed.
