The following table shows the values for gap, tightening torque (wire en-
try holes) and other data regarding the screw-on terminals of the ballast
connectors according to drive model:
The terminals (Ri, Re and L+) are used to configure the Ballast circuit
whose purpose is to dissipate the energy generated while braking the mo-
tor.
By jumpering the terminals (Ri and L+), the system is configured so as to
work with the internal resistor of the compact drive module; this configura-
tion, as mentioned earlier, can only be set for ACD/SCD/CMC 1.08/1.15
models.
Up to 45 °C (113 °F), this resistor dissipates the power indicated in the
technical data table. See table
T. H3/18 .
All the modules carry a protection against over-temperature which issues
an error E301 when reaching 105 °C (221 °F).

WARNING. On ACD/SCD/CMC 1.08/1.15 modules, if an external Ballast
resistor (for braking) is going to be connected, make sure that its Ohm va-
lue is exactly the same as that of the internal Ballast resistor. See table
T.
H3/18 which indicates this value. The rest of the compact modules have
no internal Ballast resistor; therefore, always install the external Ballast
resistor supplied by FAGOR with the unit.
NOTE. Never configure models ACD/SCD/CMC 1.25/2.35/2.50 and SCD
2.75 with internal Ballast resistor (jumper between Ri and L+). These
modules do not have an internal Ballast resistor. If this warning is ignored
and a (L+, Ri) configuration is used instead of (L+, Re), either
unknowingly or inadvertently, there is no risk of destroying the module,
but the power bus will not charge.
Remember that pin Ri has no function
in these modules.
