Dynamic Braking Resistors for Equipment of Frames 1 and 2
Frames 1 and 2 equipment include the built-in dynamic brake as standard. The user should only connect
a resistor between terminals +HVDC and B as the following drawing shows.

Note: This table is based on a 100% enable duty (ED). For other ED’s different from 100%, braking
resistors with the same ohmic value shall be used and their power shall be calculated by multiplying
the power of said resistance to 100% (value of the table) by the new ED. Enable Duty means the time
the resistor is working (regeneration). Resistors for 100% of ED = continuous operation. For example,
in case of ED of 30%, it will be multiplied by 0.3.
