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

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
