Parameter Descriptions 2-43
7000-TD002A-EN-P – September 2007
Rated Motor Voltage [Rated Motor Volt]
Linear Number: 22
Default Value: 4000 V
Minimum Value: 100 V
Maximum Value: 8000 V
Access Level: Basic
Read/Write: Read/Write when Stopped
This parameter specifies the rated line to line voltage of the motor. This parameter is internally scaled and
used as the base value in all the drive per unit calculations. The motor rated voltage should be specified
as 2300/4000V and not 2400/4160V to ensure that the line voltage is slightly higher than the motor
voltage. Since the motor voltage is limited by the line voltage, increasing the motor rated voltage in an
attempt to get more out of the drive will only force the drive to go into field weakening at a lower speed.
Service Factor [Service Factor]
Linear Number: 31
Default Value: 1.00
Minimum Value: 0.75
Maximum Value: 1.25
Access Level: Basic
Read/Write: Read/Write when Stopped
This parameter specifies the service factor of the motor. Because the motor parameters are normalized
to the service factor, changing this parameter allows the motor rating to be changed without affecting the
drive tuning.
Drive Motor Type [Motor Type]
Linear Number: 30
Default Value: Induction
Access Level: Service
Read/Write: Read/Write when Stopped
This parameter specifies the type of motor connected to the drive. If this parameter is changed, the
control power must be turned off and on before the new value takes effect.
