04 ENHANCED VARIABLE V/Hz: Achieves maximum performance for variable

torque applications . This setting may be required for high inertia fan
applications that require fast acceleration and deceleration .

05 VECTOR SPEED: Selects vector speed mode . This setting achieves

maximum performance for speed control .

06 VECTOR TORQUE: Selects vector torque mode . This setting is for

applications where torque needs to be controlled rather than speed .

NOTE
• If setting 01 or 02 is selected all parameters above 80 will be hidden . If

setting 03 or 04 is selected parameters 84, 85 and all parameters above
87 will be hidden .

• If setting 03-06 is selected the AUTO CALIBRATION (Parameter 81)

function must be performed and the appropriate motor characteristic
parameters must be programmed properly .

• If setting 06 is selected the available settings in Parameter 05 - STANDARD

REFERENCE SOURCE change . Setting 02 (normally PRESET #1),
becomes the same as setting 01 (KEYPAD) .

P81

AUTO CALIBRATION

This is used in the ENHANCED V/Hz and VECTOR modes to measure certain motor
characteristics to achieve maximum motor performance . Select setting 01 to perform the
calibration cycle on the next start command . Setting 02 cannot be selected unless the
calibration cycle has already been completed .

00 CALIBRATION NOT DONE: Drive cannot be operated in VECTOR mode if

this parameter value is 00 .

01 CALIBRATION CYCLE ENABLED: Calibration will occur on the next start

command and will take about 40 seconds to complete . Once the calibration
cycle is successfully completed, this parameter will display "02" to indicate that
the drive can run in vector mode .

02 CALIBRATION COMPLETE: The drive can be operated in vector mode .

NOTE
Prior to performing the AUTO CALIBRATION, Parameters 85-88 and 91 must
be set properly based on the motor data . Refer to Appendix B - VECTOR
MODE for more information .

P82

CURRENT LOOP P GAIN

Normally, this parameter should not require adjustment . In special cases, however, it
may need to be adjusted to optimize performance . Do not change this parameter without
consulting Lenze-AC Tech .
