3.1 Parameterising the brake chopper/brake resistor
The regenerative power supply module is equipped with an integrated brake transistor.
The required brake resistor has to be connected externally (see mounting instructions/
hardware manual).
The rated values for the brake transistor are listed in the Hardware Manual, chapter
"Rated data".
Stop!
If the connected brake resistor has a lower resistance than the parameterised
brake resistor, the brake transistor may be damaged!
The brake resistor can be thermally overloaded. Carry out protective measures
suitable for the system, e.g.:
• Parameterisation of an error response in C00574
and evaluation of the
parameterised error message in the application or machine control. I2t
utilisation of brake resistor ( 27)
• External wiring using the temperature contact on the brake resistor (e.g.
interruption of the supply via mains contactor and activation of the
mechanical brakes).
