5. Repeat this procedure with all diode supply modules.

Installation of brake resistors

A drive with option +D150 (brake copper) and option +D151 (brake resistor) have
both the chopper the brake resistor installed as standard. No installation by the
customer is needed. However, if the drive is equipped with option +D150 only, the
user must acquire and install the brake resistors according to the instructions in
