Refer to the preceding table for the model selection for a paralel inverter system.
Note:
⚫ Select braking resistors according to the resistance and power data provided by our company.
⚫ The braking resistor may increase the braking torque of the inverter. The preceding table
describes the resistance and power for 100% braking torque, 10% braking usage, 50% braking
usage, and 80% braking usage. You can select the braking system based on the actual operation
conditions.
⚫ When using an external braking unit, set the brake voltage class of the braking unit properly by
referring to the manual of the dynamic braking unit. If the voltage class is set incorrectly, the
inverter may not run properly.
 Do not use braking resistors whose resistance is lower than the specified
