4.5.5 Vector Parameters
Code Possible Settings
IMPORTANT
No. Name Default Selection
P300
(1)
Drive Mode 0 0 Constant V/Hz Constant torque V/Hz control for
general applications
1 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 1,
but cannot use Vector mode, due to:
Missing required motor data
Vector mode causing unstable
motor operation
3 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 congure the drive for either Vector mode or Enhanced V/Hz mode:
P300 = 4, 5:
- Set P302...P306 according to motor nameplate
- Set P399 = 1
- Make sure motor is cold (20° - 25° C) and apply a Start command
- Display will indicate
CAL for about 40 seconds
- Once the calibration is complete, the display will indicate
StoP; 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
F.n1d and will not operate
P300 = 2, 3: Same as above but only need to set P302…P304

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 efciency X P302 X P303 X 1.732)
cos phi = cos [ sin
-1
(magnetizing current / motor current) ]
(1) The drive can only be restarted if the error message has been reset
