See chapter 5, the section regarding the “BALLAST RESISTOR
SELECTION GUIDE
” to know whether it is necessary or not to install an
external Ballast resistor or the internal one is enough.
Resistor model
See chapter 4, section regarding “RESISTOR MODULES” to know which
external Ballast resistor corresponds when an external resistor is required in
an ACD/SCD/CMC 1.08/1.15 module.
Connection diagrams
Terminals (Ri, Re and L+) of the ACD/SCD/CMC 1.08/1.15 modules are used
to configure the Ballast circuit.
Jumpering the terminals (Ri and L+) makes it possible to dissipate the braking
energy in the internal resistor of the compact drive. Up to 45 °C (113 °F), this
resistor dissipates the power indicated in the technical data table. See table
T. H3/18.
In ACD/SCD/CMC 1.08/1.15 models, remove the jumper between (Ri and L+)
and connect an external resistor between (Re and L+) for dissipating energy.
On ACD/SCD/CMC 1.25/2.35/2.50 and SCD 2.75 models, always connect the
external resistor between Re and L+.
All the modules carry a protection against over-temperature which issues an
error code E301 when reaching 105°C/221°F.
