NOTE
1. Please select the brake unit and/or brake resistor according to the table. "-" means no
Delta product. Please use the brake unit according to the Equivalent Resistor Value.
2. If damage to the drive or other equipment is due to the fact that the brake resistors and
the brake modules in use are not provided by Delta, the warranty will be void.
3. Take into consideration the safety of the environment when installing the brake resistors.
4. If the minimum resistance value is to be utilized, consult local dealers for the calculation of
the power in Watt.
5. Please select thermal relay trip contact to prevent resistor over load. Use the contact to
switch power off to the AC motor drive!
6. When using more than 2 brake units, equivalent resistor value of parallel brake unit can't
be less than the value in the column "Minimum Equivalent Resistor Value for Each AC
Drive" (the right-most column in the table).
7. Please read the wiring information in the user manual of the brake unit thoroughly prior to
installation and operation.
8. Definition for Brake Usage ED%
Explanation: The definition of the barke usage ED(%) is for assurance of enough time for
the brake unit and brake resistor to dissipate away heat generated by braking. When the
brake resistor heats up, the resistance would increase with temperature, and brake torque
would decrease accordingly. Suggested cycle time is one minute
