Table G.13 IP67 Dynamic Brake Resistor
Note: Always check the resistor ohms against minimum resistance for drive being used.
Note: Duty Cycle listed is based on full speed to zero speed deceleration. For constance regen at full speed, duty cycle capability is half of what is listed. Application
Type 1 represents maximum capability up to 100% braking torque where possible. Application Type 2 represents more than 100% braking torque where possible, up
to a maximum of 150%.
Figure G.2 Dynamic Brake Resistor Approximate Dimensions
* Length is user-selectable based on the suffix added to the catalog number. For a length of 500±10mm, add -M05 to the end of the catalog number. For a length of
100±10mm, add -M1 to the end of the catalog number.
