8–6 Troubleshooting
Precharge Open
56 The precharge circuit was com-
manded to close, but was
detected to be open. 1. Replace the drive.
Prm Access Flt
34 A communication error occurred
between the microprocessor and
the serial EEPROM or the DSP. Record the value in [Fault Data], then
reset the fault. If this fault occurs
repeatedly, contact factory.
Reprogram Fault
48 The drive was commanded to
write default values to EEPROM. 1. Clear the fault or cycle power to the
drive.
2. Program the drive parameters as
needed.
Important: If [Input Mode] has been
changed from its original value, power
must be cycled before the new value
will take affect.
ROM or RAM Flt
68 Internal power-up ROM or RAM
tests have not executed properly. Replace Control Board or complete
drive as required.
Serial Fault
10 A SCANport adapter has been
disconnected and the [Logic
Mask] bit for that adapter is set to
“1.” 1. If no adapter was intentionally dis-
connected, check wiring to the
SCANport adapters. Replace wir-
ing, SCANport expander,
SCANport adapters, Main Control
Board or complete drive as
required.
2. If an adapter was intentionally dis-
connected and the [Logic Mask] bit
for that adapter is set to “1”, this fault
will occur. To guard against this fault
occurring, set the [Logic Mask] bit
for the adapter to “0.”
Shear Pin Fault
63 Programmed [Current Limit] amps
has been exceeded and [Shear
Pin Fault] is enabled. Check load requirements and [Current
Limit] setting.
Step Logic Flt
69 1. [SLx Step Jump] is set to “End
Fault.”
2. [Encoder Counts] has reached
the endpoint of
±
32767.
1. Check conditions that caused [SLx
Step Jump] to occur.
2. Zero [Encoder Counts]. Change
[Enc Count Scale].
Sync Loss Fault
67 Not functional at time of printing.
Temp Sense Open
55 Heat sink thermistor is open or
malfunctioning. Check thermistor and connections.
Undervolt Fault
04 DC Bus voltage fell below the min-
imum value. [Line Loss Fault] and
[Low Bus Fault] set to “enabled.” Monitor the incoming AC line for low
voltage or line power interruption.
UV Short Fault
41 Excessive current has been
detected between these two out-
put terminals. Check the motor and external wiring
to the drive output terminals for a
shorted condition.
UW Short Fault
42 Excessive current has been
detected between these two out-
put terminals. Check the motor and external wiring
to the drive output terminals for a
shorted condition.
VW Short Fault
43 Excessive current has been
detected between these two out-
put terminals. Check the motor and external wiring
to the drive output terminals for a
shorted condition.
