Torque Self- Tune Result; Reserved For Later Use - Reliance electric GV3000/SE Instruction Manual

For FVC operation (U.001 ≠ SE), this procedure determines the encoder PPR selection for parameter
U.001 (Encoder PPR). Determining the encoder PPR may be necessary since the PPR is not always listed
on the motor or encoder nameplate. Determining the magnetizing current ratio is necessary in vector
regulation so that the proper no-load current, or magnetizing current, is set. The proper magnetizing current
is required to develop rated motor torque, speed, and horsepower in vector regulation.
For FVC and SVC operation, this procedure also determines the value for parameter U.006 (Magnetizing
Current).
This parameter will be set to OFF when self-tuning is completed or aborted. This parameter only
enables self-tuning. It does not start the procedure. Parameters U.002, U.003, U.004, U.005, and
U.007 must be programmed before enabling self-tuning in U.008. Then the START key can be
pressed to start the procedure. During the test the drive will accelerate up to 90% of U.005
(Motor Nameplate RPM) even if this value is greater than the value set in P.004 (Maximum
Speed).

Torque Self- Tune Result

Parameter Range:
0 = Self-Tuning successful.
1 = User initiated a normal stop. Self-Tuning operation aborted.
2 = Emergency stop or fault stop occurred during Self-Tuning. Self-Tuning operation
aborted.
3 = Motor or encoder direction in reverse.
(CCW) direction facing motor drive end. The encoder leads might also be reversed
if the motor direction is correct.
Important: Forward means clockwise rotation viewing motor drive end, with
following conditions: Phases U,V,W at inverter output in phase with U,V,W of an
European type of motor.
4 = Encoder PPR out of range. The result of the determination of the encoder PPR was
not one of the 4 permitted values of U.001. The encoder leads might also be
reversed.
5 = Magnetizing current percent out of range. The measured no load current was not
within 10% to 80% of rated current (U.004). Check that nothing is connected to the
shaft and check the value in U.004.
6 = Bus voltage error. Bus voltage out of range. Check that the A-C input line is +/-10%
of U.018.
7 = Current limit exceeded. Self-Tuning should be run with the motor unloaded, and
without being connected to any inertia load.
Default Setting: N/A
Parameter Type: Output (read only)
Refer to: U.001 Encoder PPR
U.008 Torque Self-Tune Enable
Description: This param. shows the results of the Self-Tuning operation requested by parameter
U.008.. Normally, self-tuning should be successful and U.009 value will be 0.
SF will be displayed with a fault entry in the error log showing the cause(s) of the
fault(s) for any values of 1 through 7.
