F 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.
