Ohm values
WARNING. The Ohm value of the external Ballast resistor must be the
same as that of the internal resistor of that module.
See the tables in section “RESISTOR MODULES” of chapter 4 that show
the compact drives and the possible external Ballast resistors associated
with them.
MANDATORY. On all compact drives (except those whose reference is
SCD-NR x.xx), the external resistor supplied with the units.
ACD/SCD/CMC 1.08 /1.15 models are also an exception.
On compact drives “ACD/SCD/CMC 1.08/1.15”, as opposed to the rest of
the compact models, do not install any external Ballast resistor. The internal
one is enough, except on “SCD 1.15” models where it would be possible
to install the internal resistor ER+TH-43/350 if the application so
required.
In general, on compact models “ACD/CMC 1.08/1.15” the internal dissipation
Ballast resistor will be enough, but if it is not in a particular situation, it
is possible to install an external resistor of the same Ohm value as the internal
one and greater dissipation power.
NOTE. Actually, the external resistor provided with the unit is considered
enough for most applications. If it is not enough, install one of the same
Ohm value and greater power.
On any compact drive whose reference is SCD-NR x.xx no external Ballast
resistor will supplied with the unit. The user will place the order for the external
resistor required by the application with a FAGOR representative.
Remember that it must have the same Ohm value as the internal resistor of
the module.
