Project Info
Load type: induced draft fan
Rated voltage: 10KV
Motor rated current: 54A
Number of motor poles: 6 poles
High voltage soft start model: CMV-900-10
On-site parameter setting
Starting voltage: 65%
Current limit multiple: 4 times
Startup time: 20
After several on-site debugging, the test machine was successful when the initial voltage was 65% and the current limit was 400%.
Fan loads are light loads for inverters, but heavy loads for soft starters, especially centrifugal fans.
Generally, it is recommended to amplify a power segment in the selection of such loads. When debugging such loads, it should be noted that the current limit multiple cannot be too low, generally between 3.5-4.5 times according to the load conditions. Such loads have the characteristics of large starting current and long starting time when starting.
