Fault Legend Description
1753F 95551 30015 DynBrk Resistor RH – Dynamic braking resistor
overheat. Braking resistor unit
temperature exceeded allowable
value. (Heatsink-mount resistor
only, and only if inverter parameter
L8-01 = 1). Yes Yes Yes Minor Major Allow dynamic braking resistors to
cool before continuing operation. If
problem persists, decrease load sizes
or reevaluate dynamic braking
requirements.
17540 95552 30016 External Fault 3 EF3 – External fault signal at
terminal 3 of the inverter card. This
can be programmed to be N.O. or
N.C. contact. Yes Yes Yes Minor Major A fault has occurred in circuits
outside the Smart Trac AC1 inverter
card. Troubleshoot and correct. The
input labeled ‘Major’ will be true
only if inverter parameter H1-01 = 20
to 2B hex.
17541 95553 30017 External Fault 4 EF4 – External fault signal at
terminal 4 of the inverter card. This
can be programmed to be N.O. or
N.C. contact. Yes Yes Yes Minor Major A fault has occurred in circuits
outside the Smart Trac AC1 inverter
card. Troubleshoot and correct. The
input labeled ‘Major’ will be true
only if inverter parameter H1-02 = 20
to 2B hex.
17542 95554 30018 External Fault 5 EF5 – External fault signal at
terminal 5 of the inverter card. This
can be programmed to be N.O. or
N.C. contact. Yes Yes Yes Minor Major A fault has occurred in circuits
outside the Smart Trac AC1 inverter
card. Troubleshoot and correct. The
input labeled ‘Major’ will be true
only if inverter parameter H1-03 = 20
to 2B hex.
