Description
F282
Syncxfer fail
W A synchronous transfer was not completed within the time specified
by parameter Sync xfer time (P230). The drive will continue to run.
F283
Not used
W
F284
Com proc brd
W
Indicates that the communication board is not communicating with
drive control board or the board has failed self-power test, which
requires recycling of the power.
F285
Adapter loss
W The drive has lost communication with a SCANport adapter.
F286
Spd cmd loss
W
The drive has lost communication with the SCANport adapter
providing the speed command.
F287
Local loss
W
F288
Tuning abort
W Autotuning was unable to complete the measurement of the tuning
parameter with in allowed time.
F289
In test mode
W Indicated that the drive is set in a test mode
F290
Reg in limit
W Speed regulator or flux regulator hit the limit during auto tuning and
the auto tune results are not valid.
F291
R stator hi
W Indicated the motor cables are extremely long.
F292
Time limit
W Indicates the autotuning could not measure the parameter with in
allowed time limit.
F293
Inertia high
W Indicates that the measure inertia is greater than 5.0 sec.
F294
L comm low
W Indicates the measured commutation inductance is less than 0.02
pu. Require manual tuning of commutation inductance.
F295
L comm high
W Indicates the measured commutation inductance is greater than
0.15pu. Require manual tuning of the commutation inductance.
F296
T dc low
W Indicates the measured DC link time constant is less than 0.020 sec.
Require manual tuning of DC link time constant.
F297
T dc high
W Indicates the measured DC link time constant is greater than
0.100sec. Require manual tuning of DC link time constant.
F298
L leakage lo
W Indicates the measured leakage inductance is less than 0.15pu.
F299
L leakage hi
W Indicates the measured leakage inductance is greater than 0.30pu.
F300
L magn low
W Indicates the measured magnetising inductance is less than 2.0pu.
Require manual tuning for flux regulator.
F301
L magn hi
W Indicates the measured magnetising inductance is greater than
10.0pu. Require manual tuning for flux regulator.
F302
T rotor low
W Indicates the measure rotor time constant is less than 0.2sec.
It requires manual tuning of rotor time constant.
F303
T rotor high
W Indicates the measure rotor time constant is greater than 5.0sec.
It requires manual tuning of rotor time constant.
