Motor service factor
Parameter Motor service factor specifies the ratio of the actual maximum power of
the motor to its nameplate rated power.
Units
Motor service factor is a unitless number.
Motor winding cfg
Parameter Motor winding cfg specifies the winding configuration of the motor.
The following values are available for Motor winding cfg:
• Wye E-LN=Sqrt3*E-PH: Wye configuration.
• Delta E-LN = E-PH: Delta configuration.
The motor data sheet often lists the motor line voltage and phase voltage in place of
the winding configuration. If the motor data sheet specifies E-LN for the line voltage
and E-PH for the phase voltage, then the winding configuration can be determined
using the following relationships:
Wye configuration: E-LN =
3 x E-PH
Delta configuration: E-LN = E-PH
Preflux Forcing
Parameter Preflux Forcing specifies the amount of peak current use to pre-flux the
motor. The dimension is in per unit of motor nameplate amps. It is recommended to
use 1.0 per unit field-forcing; however, in cases where motor rating is higher than
inverter rating, the field-forcing Amps may have to be reduced to avoid inverter
thermal overload during pre-fluxing. In general, using higher field-forcing Amps can
reduce pre-flux duration.
