6. Inverter
The following section details fault numbers assigned to the Smart Trac AC1 Inverter (Power Conversion Unit).
Notes:
•
Inverter faults will be declared only if properly setup in Fault Manager, DPRAM Interface Card, and the application program.
•
These faults are declared when the inverter sees them as major faults. As Minor faults, these fault codes are not generated but drive may still set a minor fault bit.
•
All Inverter faults listed here correspond to those found in MagneTek’s GPD515 Technical Manual.

Fault Legend Description
17530 95536 30000 DC Bus Fuse Open PUF – Fuse blown. DC fuse has
cleared. Yes Yes Yes Minor Major Check for short circuit in output
circuitry. Possibility of motor
windings T1, T2 and/or T3 shorted.
Possibility of drive output phases
shorted to ground. Possibility power
transistors are damaged.
17531 95537 30001 DC Bus Undervolt UV1 – Main circuit undervoltage.
Occurs 2 seconds after detection of
low voltage. Detection levels:
190VDC for 230V rated unit;
380VDC for 460V rated unit;
546VDC for 600V rated unit. Yes Yes Yes Minor Major Check input AC supply. Possibility
of erroneous operation due to noise:
remove noise source by connecting
surge suppressor to relay and
magnetic contactor coils; provide line
filter to remove noise on input power
line. Possibility of gate drive PCB is
faulty. Note: fault is declared only if
drive is in Run mode.
17532 95538 30002 CTL PS Undervolt UV2 – Control circuit undervoltage.
Control circuit voltage is low during
operation. Yes Yes Yes Minor Major Possibility of poor DC supply being
furnished by drive. Note: fault is
declared only if drive is in Run
mode.
