Visible only if Motor parameter choice MPC page 58 is set to CoS. If Rated motor cos phi CoS is available
Rated motor power nPr disappears.
Motor nameplate power factor (pf).
Note: Do not confuse this with motor "Service Factor". Setting CoS to or very near to 1 may result in
unsatisfactory motor operation. If the motor power factor is not indicated on the nameplate, leave this
parameter at the factory default (approximately 0.80)
UnS
• Rated motor voltage
100 to 480 V 230 V
Rated motor voltage given on the nameplate. If the line voltage is less than the rated motor voltage, Rated
motor voltage UnS should be set to the value of the line voltage applied to the drive terminals.
nCr
• Rated motor current
0.25 In to 1.5 In

According to drive rating
Rated motor current given on the nameplate. Rated motor current nCr modifies Motor thermal current ItH

FrS
• Rated motor frequency
10 to 400 Hz 50 Hz
Rated motor frequency given on the nameplate.
The factory setting is 50 Hz, or preset to 60 Hz if Standard motor frequency bFr page 44
is set to 60 Hz.
nSP
• Rated motor speed
0 to 24000 rpM According to drive rating
Rated motor speed given on the nameplate.
tFr
• Maximum frequency
10 to 400 Hz 60 Hz
Maximum frequency tFr gives the upper value possible for High speed HSP page 76.
The factory setting is 60 Hz, or preset to 72 Hz if Standard motor frequency bFr page 55
is set to 60 Hz.

PUMP
Allows selection of the motor control type suitable for the application and the required performances.
• Performance: SVCU; Sensorless vector control with internal speed loop based on voltage feedback
calculation. For applications needing high performance during starting or operation.
• Standard: U/F 2 points (Volts/Hz) without internal speed loop
For simple applications that do not require high performance. Simple motor control law keeping a constant
Voltage Frequency ratio, with a possible adjustment of the curve bottom.
This law is generally used for motors connected in paralell. Some specific applications with motors in
paralell and high performance levels may require PErF.
• Pump: U
2
/F; dedicated to variable torque pump and fan applications that do not require high starting torque.
