MESSAGE
F Description
F0 Line selftst F The line converter control board has failed its power up self-test. This
fault can only be cleared by turning off the control power.
F1 Line param F The parameters stored in EEPROM on the Line Converter control
board have been corrupted.
F2 Line s/w w/d F Line side software watchdog has expired.
F3 Line h/w w/d F Line side hardware watchdog timer has expired
F4 Line s/w o/c F The line current feedback has exceeded the level in P161 for the
duration in P162.
F5 Line h/w o/c F The instantaneous line current has exceeded the level in P169 for the
duration in P170.
F6 Line ac o/v F The line voltage has exceeded the level in P165 for the duration in
P166
F7 Line dc o/v F The line side dc link voltage has exceeded the level in P187 for the
duration in P188.
F8
12p phasing
or
Line phasing F This fault indicated on 12 or 18 pulse drives only. Either the phase
rotation of the line voltage is reversed or the phase angle relationships
between the slave bridge(s) and the master bridge is incorrect.
Firmware revision numbers less than 5.00 termed “12 p phasing”
Firmware revision numbers grea
ter than 5.00 termed “Line phasing”
F9 Ground fault F The signal from the ground fault CT has exceeded the level in P171
for the duration in P172.
F10 Line thy open F An open thyristor has been detected in the line converter.
F11 Line thy short F A shorted thyristor has been detected in the line converter.
F12 Ac cntrl pwr F The 48Vdc-power supply has reported an AC voltage fault. Check
control power supply.
F13 Ln unbalance F The unbalance in the line voltage or current feedback is greater than
0.1 pu for more than 100 cycles. If the drive is running it is a current
balance fault, and if the drive is not running it is a voltage balance fault.
F14 Input open F The input contactor has opened when the drive was running.
F15 Pulse number F Parameter Pulse Number (P153) has been changed and the drive
control power was not cycled.
F16 Mtr selftst F The machine converter control board has failed its power up self-test.
This fault can be cleared only by turning off the control power.
F17 Mtr parm F The parameters stored in EEPROM on the Machine Converter
Control Board have been corrupted.
F18 Mtr s/w w/d F Motor side software watchdog timer has expired.
F19 Mtr h/w w/d F Motor side hardware watchdog timer has expired.
F20 Mtr s/w o/c F The motor current has exceeded the level in P177 for the duration in
P178.
F21 Mtr h/w o/c F The motor current has exceeded the level in P177 for the duration in
P178.
F22 Mtr ac o/v F The motor voltage has exceeded the level in P181 for the duration in
P182.
F23 Mtr dc o/v F
The motor side DC link voltage has exceeded P187 for the duration in
P188.
