Figure 235 - Motor Filter Capacitor
WARNING: Allow 5-10 minutes for motor capacitors to safely discharge voltage
prior to opening cabinet doors.
WARNING: The following fault codes may also indicate a non-operational
Motor Filter Capacitor (MFC):
F96 (Motor Overcurrent Fault)
F98 (Motor Neutral Overvoltage Fault)
F99 (Motor Flux Unbalance Fault)
F100 (Motor Current Unbalance Fault)
F103 (Motor Stall Fault)
F113 (DC Link Overcurrent Fault)
F114 (Ground Overcurrent Fault)
F115 (Neutral Resistor Overcurrent Fault)
F145 (Neutral Resistor Overload Fault)
Do not reset these faults until you have determined the root cause of the fault.
Operating a synchronous transfer system (specifically during the ‘Transfer to
Drive’ operation, also known as the de-sync operation) with a non-operational
MFC can lead to serious personal injury and/or property damage.
