Resistor braking
126
With Standard Application Program, wire the thermal switch as shown below. By
default, the drive will stop by coasting when the switch opens.
For other application programs, the thermal switch may be wired to a different digital
input. Programming of the input to trip the drive by “EXTERNAL FAULT” may be
needed. See the appropriate firmware manual.
Brake circuit commissioning
For Standard Application Program:
• Enable the brake chopper function (parameter 27.01).
• Switch off the overvoltage control of the drive (parameter 20.05).
• Check the resistance value setting (parameter 27.03).
• Frame sizes R6, R7 and R8: Check the setting of parameter 21.09. If stop by
coasting is required, select OFF2 STOP.
For the use of the brake resistor overload protection (parameters 27.02...27.05),
consult an ABB representative.
WARNING!
If the drive is equipped with a brake chopper but the chopper is not
enabled by parameter setting, the brake resistor must be disconnected because the
protection against resistor overheating is then not in use.
For settings of other application programs, see the appropriate firmware manual.
