High overload
output power
in kW
Note:
High overload output power: output power @160% Torque
Normal overload: output power @110% torque, it is the power printed in the nameplate.
For example:
T/C: CDS303P15KT4E20H2-P15K high overload output power, take the reference of drive nomenclature
18.5kW(400V)-normal overload power, power printed in the nameplate.
Please note in this guideline, only drive power use high overload power; all the other data, such as fuses/circuit breaker, etc. is reference to Normal overload power.
