4.3.3 Ohm value
The user will select the required resistor model to be installed according
to table T. H4/10 and depending on the energy to be dissipated in the
application. FAGOR supplies the resistor upon request.
Therefore, use the attached table to select the resistor for your QC-PS-
module with enough rms dissipation power to dissipate the energy
generated while braking.
Installation
See section, 8.5.6 CONNECTING THE EXTERNAL BRAKING RESISTOR(S) TO NON-
REGENERATIVE POWER SUPPLIES.
Chapter 11. DIMENSIONS of this manual shows the dimensions.
WARNING. When connecting an external Ballast resistor, make sure that
its Ohm value is exactly the same as the one shown in the technical
characteristics table for the corresponding non-regenerative power supply
in chapter 2. POWER SUPPLIES of this manual.
