Presenting the Required Specifications to the Resistor Manufacturer

Provide the following information to the manufacturer of your resistors and select a dynamic
brake resistor that is appropriate for the required specifications.
Required Information for Resistor Selection
Resistance [Ω]
Resistor energy consumption for one operation of the
dynamic brake [J]
Number of dynamic brake operations (estimated number of
emergency stops required during the product life of your
system)
Wire sizes and crimped terminals
Note: The applicable wire sizes depend on the SERVOPACK
model.
Resistor Selection Example for a Dynamic Brake That Operates 1,000 Times
Example
Refer to the following manual for the external dimensions of the dynamic brake resistor and
other parts in the selection example.
