Resistor braking

What this chapter contains

This chapter describes how to select, protect and wire brake choppers and resistors.
The chapter also contains the technical data.
Availability of brake choppers and resistors for the
ACS800
Frame R2 and R3 drives and 690 V units of frame size R4 have a built-in brake
chopper as standard equipment. For other units, brake choppers are optionally
available as built-in units, indicated in the type code by +D150.
Resistors are available as add-on kits.
Selecting the correct drive/chopper/resistor
combination
1. Calculate the maximum power
2. Select a suitable drive / brake chopper / brake resistor combination for the
application according to the following tables (take account of other factors in
(P
) generated by the motor during braking.
