Drive Mode
1
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 or 2 (if option 1 failed or in case of non-standard motor)
- 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

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
