22.7 – FUNCTIONS/BRES OVERLOAD
Braking resistors may be subject to sudden overloads following failures.
Always protect resistors by using thermal protection devices.
These devices do not have to interrupt the circuit where the resistor is installed, but their auxiliary contact must
interrupt the power supply of the drive power section. If the resistor requires the presence of a protection con-
tact, this must be used together with the one belonging to the thermal protection device.

Parameters IPA 3272 Bres enable src and IPA 3274 Bres enable inv manage enabling/disabling (by digital
input) of the internal BU connected to a braking resistance with or without protective klickson.
The internal BU must be enabled with parameter IPA 3250 Bres control.
It can be used two ways:
1) If you use a resistance with klickson, the protection contact can be linked to a digital input by appropri-
ately conguring IPA 3272 from selection list L_DIGSEL1. The digital input will enable the braking when
the temperature of the resistance is below the protection threshold or disable it when the temperature
exceeds the threshold.
2) If you use a resistance without klickson, you can use the state of an alarm such as (for example) [15]
Bres overload to enable the braking unit when the alarm is inactive:
- congure IPA 3272 Bres enable src = IPA 4708 Alm dig out mon 1 (from selection list L_DIGSEL1),
- set IPA 4700 Alarm dig sel 1 = [15] Bres overload,
- set IPA 3274 Bres enable inv = 1 to invert the logic state.
