Function:
Function:
No brake resistor installed.
Brake resistor incorporated in the system, for dissipation of surplus brak-
ing energy as heat. Connecting a brake resistor allows a higher DC link
voltage during braking (generating operation). The resistor brake func-
tion is only active in adjustable frequency drives with an integral dynamic
brake.
AC Brake will only work in Compressor Torque mode in par.1-03
