application to another, but the basic idea is always the same, to dissipate the required power to
decelerate the load in desired time.
NOTE
: Brake resistor wires’ insulation grade must be higher than
1000Vac and 3000Vdc.

External Brake Resistor Installation
Step 1: Check the Brake Resistor
Check the external brake resistor
’s
resistance, maximum absorb energy and maximum power.
Make sure that the brake resistor is suitable for AxN Size4 Drive and real application.
Step2: Find out the External Brake Resistor Terminals
DC+ and Brk-, these are the two terminals called External Brake Resistor Terminals. AxN Size4
Drive
’s Internal Brake Resistor Terminals are in the Power Supply Input Port (P1) which
is on the
top of the drive. Refer to the following figures for exact locations and terminal Assignment.
Step3: Insert Wires into Corresponding Terminals
Use a 3mm hexagonal wrench to loosen the hexagonal screws on DC+ and Brk- Terminals which
are in the drive’s Power Supply Input Port (P1). Insert the two wires of the external brake resistor
separately into these two terminals.
NOTE:
The metal part of the wire should be fully inserted into corresponding terminals. Leave only
the insulated part outside.
