IP67 Dynamic Brake Resistor Ratings
Table A.1 IP67 Dynamic Brake Resistor
* - Indicates cable length (0.5 m or 1.0 m).
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%.
