WARNING. When connecting an external braking resistor other than the
one shown in table T. H4/9 make sure that its Ohm value is the same as that
of the internal Ballast resistor of the unit. Verify it in the technical
characteristics table of the corresponding power supply in chapter 2 or of the
corresponding compact drive in chapter 3 of this manual.
ACD/CMC/SCD compact units without NR model have a particular resistor
associated with them; FAGOR supplies it in an accessory bag inside the
unit package and the user must install it. This is not the case for units with
NR model for which the user must select the appropriate resistor model
depending on the energy to be dissipated in the application. Therefore, the
latter do not come with the resistor in the accessory bag of the unit and it
must be requested separately.
Use the attached table to select the external Ballast resistor for your power
supply with enough RMS power to dissipate the energy generated while
braking.
