Ohm value
WARNING. When connecting an external braking resistor other than the
one shown in table T. H4/8 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 reference 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 reference 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.
