12.3 Input Frequency and Voltage Tolerance
The AC supply voltage must be within the required voltage range of 240/480 VAC +10% to –5%
to maximize motor power production.
The standard product with three-phase voltage input has an allowable range of +10% to –15%.
A stricter input voltage tolerance of +10 to –5% applies when using the drive with a single-
phase supply. The average bus voltage with single-phase input is lower than the equivalent of a
three-phase input. Therefore, the maximum output voltage (motor voltage) will be lower with a
single-phase input.
The minimum input voltage must be no less than 228 VAC for 240 volt models and 456 VAC for
480 V models, to ensure motor voltage production of 207 VAC and 415 VAC, respectively.
If full motor torque must be developed near the base speed (full power) it will be necessary to
maintain a rigid incoming line voltage so that adequate motor voltage can be produced.
Operating a motor at reduced speed (reduced power), or using a motor with a base voltage
that is lower than the incoming AC supply rating (ex. 208 VAC motor with a 240 VAC supply) will
also minimize the effect of voltage deprivation ( 240 VAC Input for 208 V motor, 480 VAC Input
for 400 V motor).
