4.1 Braking resistors
4.1.1 Description
The PM340 Power Modules cannot regenerate into the line supply. For regenerative
operation, e.g. the braking of a rotating mass, a braking resistor must be connected to
convert the resulting energy into heat.
A thermostatic switch monitors the braking resistor for overtemperature and issues a signal
on a floating contact if the limit value is exceeded.
4.1.2 Safety information
CAUTION
The surface temperature of the braking resistors may exceed 80 °C.
The braking resistor is connected directly on the Power Module at the terminals DCP/R1 and
R2.
The braking resistor must be protected against overheating. A thermoswitch handles this
protective function (included in the scope of supply of each breaking resistor). There are two
ways of using this thermoswitch to protect the braking resistor.
