Note:
Select the resistor and power of the braking unit according to the data our company
provided.
The braking resistor may increase the braking torque of the inverter. The resistor power in
the above table is designed on 100% braking torque and 10% braking usage ratio. If the
users need more braking torque, the braking resistor can decrease properly and the power
needs to be magnified.
When using the external braking units, please see the instructions of the energy braking
units to set the voltage degree of the braking unit. Incorrect voltage degree may affect the
normal running of the inverter.
 Never use a brake resistor with a resistance below the minimum value
specified for the particular drive. The drive and the internal chopper are not
able to handle the overcurrent caused by the low resistance.
 Increase the power of the braking resistor properly in the frequent braking
situation (the frequency usage ratio is more than 10%).
D.8.2 AC 3PH 380V(-15%)~440V(+10%)
The inverters of 660V have optional braking units. Please select the braking resistor
according to actual operation.
