Bus Protection Module
Available models:
QC-BPM-100
QC-BPM-100 commercial model is installed in QC-PDS systems where
there is a:
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
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
braking 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.

QC-BPM-100
MANDATORY.
It is ALWAYS be mandatory to install on the QC-BPM-100
bus protection module at least one to a three ER+TH-18/1100 external
braking resistors in parallel, without power limit, depending on the needs
required by the application. See section,
BRAKING RESISTORS FOR THE QC-BPM-100
