Curtis AC F2-A, F4-A, F6-A Motor Controllers – FOS 4.5 – April 2022

TROUBLESHOOTING CHART

POSSIBLE CAUSES
1. External short of phase U, V, or W
motor connections.
2. Speed encoder noise problems.
3. Motor parameters are mistuned.
4. Controller defective.
1. Leakage to vehicle frame from
phase U, V, or W (short in
motor stator).
2. Controller defective.
1. An external load on the capacitor
bank (B+ connection terminal)
that prevents the capacitor bank
from charging.
2. See Programmer » System Monitor
menu » Controller » Capacitor
Voltage.
SET/CLEAR CONDITIONS
Set: Phase current exceeded
the current measurement limit.
Clear: Reset Controller.
Set: Controller current sensors
have invalid offset reading.
Clear: Reset Controller.
Set: The precharge failed to
charge the capacitor bank.
Clear: Cycle Interlock or Reset
Controller.
