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 configure 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 efficiency X P302 X P303 X 1.732)
cos phi = cos [ sin

(magnetizing current / motor current) ]

The drive can only be restarted if the error message has been reset
