Torque vector control will not work correctly if more
than one motor is to be driven from one drive or if
the motor does not have either 2, 4, or 6 poles. If
either of these situations apply, torque vector control
should be made inactive. If the motor cables exceed
164 feet (50m) in length, or if filters or reactors are
connected between the drive and the motor, the auto-
tune feature (see Function Code 90) may not be able
to measure the motor parameters accurately enough
to provide the specified performance. However, torque
vector control may still be used if performance is
adequate for the application.
For your convenience we have pre-installed the
parameters for the 4-pole GE Energy $aver® motor
with horsepower rating corresponding to the drive
rating. If you are using any other motor you should set
Function Code 04 (Rated Voltage #1) and Function
Code 28 (Slip Compensation) per the motor's name-
plate and use Function Code 90 (Motor Tuning) so the
drive can learn the motor's equivalent circuit para-
meters (Function Code 91 and 92.)
WARNING: An incorrect setting in Function Code 87 (Motor Full Load Current),
Function Code 88 (Motor No Load Current), Function Code 91 (% Motor Resistance),
and Function Code 92 (% Motor Impedance) will cause an error in the torque
calculation. This could result in motor hunting or abnormal vibration. If a STOP
command is applied, the motor could decel at a slow rate and if that rate exceeds
three (3) times the decel time setting, Torque Limiting (Braking) setting, Function
Code 16, will be ignored.
