Which factors will affect VFD output torque?
Heating and cooling capacity to determine the variable frequency drive output current capability, thus affect its output torque capability.
Carrier Frequency: generally the variable frequency drive rated current is the continuous output value under the highest carrier frequency, the maximum ambient temperature. Reduce carrier frequency won't affect the motor current, but will reduce electronic devices heating.
Ambient temperature: like will not increase VFD drive protection current when detect relative low ambient temperature.
Altitude: altitude increases will affect both heating and insulating property of the variable frequency drive. Generally it's fine in below 1000m, and derate 5% per 1000meters for above.
