When AC Drive is equipped with a DC reactor, please read user manual to know th
wiring method of input circuit of brake unit +(P).
Do Not connect input circuit -(N) to the neutral point of the power system.
2. If damage to the drive or other equipment is due to the fact that the brake resistors and 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. If the
minimum resistance value is to be utilized, consult local dealers for the calculation of Watt figures.
4. 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). Please read the wiring information in the user manual of brake unit thoroughly
prior to operation
5. This chart is for normal usage; if the AC motor drive is applied for frequent braking, it is suggested to
enlarge 2~3 times of the Watts.
6. Thermal
Relay:
Thermal relay selection is basing on its overload capability. A standard braking capacity for C2000 is
10%ED (Tripping time=10s). The figure below is an example of 406V, 110kw AC motor drive. It
requires the thermal relay to take 260% overload capacity in 10s (Host starting) and the braking
current is 126A. In this case, user should select a rated 50A thermal relay. The property of each
thermal relay may vary among different manufacturer, please carefully read specification.
