4.5.5 Vector Parameters
Code Possible Settings
IMPORTANT
No. Name Default Selection
() Drive Mode 0 0 Constant V/Hz Constant torque V/Hz control for
general applications
 Variable V/Hz Variable torque V/Hz control for
centrifugal pump and fan applications
2 Enhanced Constant V/Hz For single or multiple motor
applications that require better
performance than settings 0 or , but
cannot use Vector mode, due to:
• Missing required motor data
• Vector mode causing unstable motor
operation
 Enhanced Variable V/Hz
4 Vector Speed For single-motor applications requiring
higher starting torque and speed
regulation
5 Vector Torque For single-motor applications requiring
torque control independent of speed
Note
To configure the drive for either Vector mode or Enhanced V/Hz mode:
• P00 = 4, 5:
- Set P02...P0 according to motor nameplate
- Set P99 = 
- Make sure motor is cold (20° - 25° C) and apply a Start command
- Display will indicate
for about 40 seconds
- Once the calibration is complete, the display will indicate ; apply
another Start command to actually start the motor
- If an attempt is made to start the drive in Vector or Enhanced V/Hz
mode before performing the Motor Calibration, the drive will display
and will not operate
• P00 = 2, : Same as above but only need to set P02…P04
() Motor Rated
Voltage 0 {V} 00
• Default setting = drive rating
• Set to motor nameplate data
() Motor Rated
Current 0.0 {A} 500.0
() Motor Rated
Frequency 0 0 {Hz} 000
Set to motor nameplate data () Motor Rated
Speed 750 00 {RPM} 5000
() Motor Cosine Phi 0.80 0.40 0.99
Note
If motor cosine phi is not known, use one of the following formulas:
cos phi = motor Watts / (motor efficiency X P02 X P0 X .72)
cos phi = cos [ sin
 (magnetizing current / motor current) ]
() Any changes to this parameter will not take effect until the drive is stopped
