If the application requires dynamic braking to dissipate motor generated energy, an optional external
braking assembly or kit will be required. The type of dynamic braking assembly or kit depends on the
specific control model and user preference. The available assemblies and kits that will fit a given
control depend on the control catalog number suffix.
CAUTION:
DB SHOULD NOT BE USED IN APPLICATIONS REQUIRING CONTINUOUS
BRAKING (REGENERATION).
Control Catalog Numbers with an "E" Suffix
These controls come equipped with both the dynamic braking transistor and braking resistor factory
installed. This configuration is capable of providing 100% braking torque for 6 seconds of a 20%
braking duty cycle. Should additional braking capacity be required an optional externally mounted
braking resistor hardware is required.
This hardware is available in two configurations:
1)
RG Kit-includes braking resistors mounted on brackets and the resistors are wired
together for the correct equivalent resistance required by the braking transistor.
2)
RGA Assemblies-includes braking resistors on brackets, wired together for correct
resistance and mounted in a NEMA 1 screened enclosure.
A listing of RGA assemblies available follows in Table 2.3.
Control Catalog Numbers with an "ER" Suffix
These controls have the dynamic braking transistor installed at the factory but no dynamic braking
resistors. Should you need dynamic braking capacity optional separately mounted external braking
resistor kits or assemblies are available from Baldor.
One hardware configuration is the RG kit which comes with resistors mounted on brackets and the
resistors wired together for the correct resistance required by the control's DB transistor. These
resistors must be mounted in an enclosure by the customer.
The other DB hardware configuration available is the RGA Assembly. It includes the resistors on
brackets and the resistors wired together all mounted in a NEMA 1 screened enclosure.
A listing of available RGA assemblies follows in Table 2.3.
