Braking resistors
Used to dissipate any excess energy generated by the
DC power BUS during electric motor braking. They do
not need an external power supply.
Bus protection module
Install in QC-PDS systems having:
Synchronous spindle and only when required by the
application.
Purpose. Protect the power semi-conductors (IGBTs)
of the drive that governs it to prevent damage to the
unit due to a very high voltages that may be
generated at the power bus when the braking energy
cannot be returned during braking and/or
QC-RPS-
-F
power supply when only the
controlled stop is to be ensured.
Purpose
. To ensure a controlled stop of the motor due
to mains failure because the energy may be
dissipated while braking at the external Ballast
resistors installed in the QC-BPM-100 module. Not
installing this module will result in an uncontrolled
stop (by friction) in case of a voltage failure due to an
over-voltage error of the bus because there are no
resistors to dissipate the braking energy.

MANDATORY. ALWAYS install an external braking
resistor. Select the resistance according to the dissipated
power based on the application. See table.

WARNING. HEAT DANGER. DO NOT TOUCH the surface of
these resistors. Remember that they can sometimes
exceed temperatures of 300 °C (572 °F). If it is installed
in an easily accessible location, precautions must be
taken to prevent unintentional contact. Also avoid heat
sensitive items (cables, etc.) from coming into contact
with the surface to avoid damaging or destroying these
elements and/or causing other more dangerous
situations.

WARNING.
The DC BUS discharge period may extend for up to
10 min after the equipment has been disconnected from the elec-
trical mains. For this reason, always
ensure that there is no volt-
age in the DC BUS before handling the equipment.
