Brake Circuit Commissioning - ABB ACS800-04 Hardware Manual

Brake circuit commissioning

For Standard Control 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).
•
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 has a brake chopper but the chopper is not enabled
by a parameter setting, disconnect the brake resistor because the
protection against resistor overheating is not in use.
For settings of other control programs, see the appropriate firmware manual.
Note: Some brake resistors are coated with oil film for protection. At the start-up,
the coating burns off and produces a little bit of smoke. Ensure proper ventilation at
the start-up.
