Vector mode

Use the following procedures to select either Vector mode or Enhanced V/Hz mode. Enhanced V/Hz
mode should be used in the following cases:
1.
Multiple motor applications
2.
Where required motor data is not available (especially C91)
3.
Where running in Vector mode causes unstable motor operation
4.4.1

Vector speed and torque modes

1.
Connect the controller to the motor according to the diagram in Section 3.2.3.
2.
Apply power to the controller.
3.
Set C14 to 4 for Vector speed mode, or 5 for Vector torque mode.
4.
Set C86...C91 according to the motor's nameplate data.
5.
Set c48 to 1 to enable the motor calibration function.
6.
Make sure the motor is cold (rotor and windings are at room temperature of 20º to 25º C), and
apply a HIGH signal at terminal 28. The display will show CAL for about 40 seconds. Once the
calibration is complete, the display will show OFF or 1nh. Apply another HIGH signal to terminal
28 to actually start the motor.
4.4.2

Enhanced V/Hz mode

Follow the procedure in 4.4.1 above, replacing steps 3 and 4 with those below:
3.
Set C14 to 6 for Enhanced with Auto-Boost, or 7 for Enhanced with constant boost.
4.
Set C88...C90 according to the motor's nameplate data.
Note
• If the motor is hot when the motor calibration is performed, the controller will not
be able to achieve maximum performance.
• In Vector speed and Vector torque modes, if an attempt is made to start the
controller before performing the motor calibration, the controller will display n1d
and the motor will not operate.
