Fault Codes - Carrier MOTORMASTER 48/50P3 Installation Instructions Manual

The drive uses a electronic programming
EPM Chip —
module (EPM) chip to store the program parameters. This is an
EEPROM memory chip and is accessible from the front of the
VFD. It should not be removed with power applied to the
VFD.
Loss of CCN Communications —
Network (CCN) communications with external control
®
systems can be affected by high frequency electrical noise
The drive is programmed to automatically restart after a fault and will attempt to restart three times
after a fault (the drive will not restart after CF, cF, GF, F1, F2-F9, or Fo faults). If all three restart attempts
are unsuccessful, the drive will trip into FAULT LOCKOUT (LC), which requires a manual reset.

PROBABLE CAUSE
METHOD
Automatic Ambient temperature is too high;
Cooling fan has failed (if equipped).
Manual A blank EPM, or an EPM with cor-
rupted data has been installed.
Manual An EPM with an incompatible param-
eter version has been installed.
Manual The EPM is missing or damaged.
Manual The control board has sensed a
problem
Manual User data and Carrier defaults in the
EPM are corrupted.
Automatic Line voltage is too high; Deceleration
rate is too fast; Overhauling load.
Automatic The watchdog timer has timed out,
indicating that the serial link has been
lost.
Automatic Line voltage is too low.
Automatic Phase to phase or phase to ground
short circuit on the output; Failed out-
put transistor; Boost settings are too
high; Acceleration rate is too fast.
Automatic VFD is undersized for the application;
Mechanical problem with the driven
equipment.
Automatic Single-phase input power has been
applied to a three-phase drive.
Automatic Start contact is missing or not
functioning.
Automatic Start contact not closed.
Automatic Speed signal lost. Drive will operate
at 57 (or 47) Hz until reset or loss of
start command. Resetting requires
cycling start command (or power).

CORRECTIVE ACTION
Check cooling fan operation.
Perform a factory reset using Parameter
48 – PROGRAM SELECTION. See Drive
Programming section.
Either remove the EPM or perform a fac-
tory reset (Parameter 48) to change the
parameter version of the EPM to match
the parameter version of the drive.
Install EPM or replace with new EPM.
Consult factory.
Restore factory defaults by toggling P48 to
another mode. Then set P48 to desired
mode to restore all defaults for that mode.
See Drive Programming section. If that
does not work, replace EPM.
Check line voltage — set P01
appropriately.
Check serial connection (computer).
Check settings for P15.
Check settings in communication software
to match P15.
Check line voltage — set P01
appropriately.
Reduce boost or increase acceleration
values. If unsuccessful, replace drive.
Check line voltage – set P01 appropri-
ately.
Check for dirty coils.
Check for motor bearing failure.
Check input power phasing.
Check fan relay.
Check FR for closed contact.
Transducer signal lost. Check VDC signal
between TB5 and TB2. Should be in range
of 0.5V to 4.5V. 5VDC output should be
present between TB6 and TB2.
V control. Ensure unit is well
