Table 41 — Fault Codes (cont)
DESCRIPTION AND RECOMMENDED CORRECTIVE ACTION
Field bus communication has timed out. Check fault setup (3018 COMM FAULT FUNC and
3019 COMM FAULT TIME). Check communication settings (Group 51 or 53 as appropriate).
Check for poor connections and/or noise on line.
Error in reading the configuration file for the field bus adapter.
Fault trip forced by the field bus. See the field bus reference literature.
Fault code reserved for the EFB (Embedded Field Bus) protocol application. The meaning is
protocol dependent.
Fault code reserved for the EFB protocol application. The meaning is protocol dependent.
Fault code reserved for the EFB protocol application. The meaning is protocol dependent.
Fault in the motor circuit. One of the motor phases is lost. Check for motor fault, motor cable
fault, thermal relay fault (if used), or internal fault.
Error in power wiring suspected. Check that input power wired to drive output. Check for
ground faults.
Error internal to the drive. Contact Carrier and report the error number.
Error internal to the drive. Contact Carrier and report the error number.
Parameter values are inconsistent. Check for any of the following:
2001 MINIMUM SPEED > 2002 MAXIMUM SPEED
2007 MINIMUM FREQ > 2008 MAXIMUM FREQ
2001 MINIMUM SPEED / 9908 MOTOR NOM SPEED is outside of the range: –128 to +128
2002 MAXIMUM SPEED / 9908 MOTOR NOM SPEED is outside of the range: –128 to +128
2007 MINIMUM FREQ / 9907 MOTOR NOM FREQ is outside of the range: –128 to +128
2008 MAXIMUM FREQ / 9907 MOTOR NOM FREQ is outside of the range: –128 to +128
Parameter values are inconsistent. Check that 2007 MINIMUM FREQ is negative, when
8123 PFA ENABLE is active.
Parameter values are inconsistent. The number of programmed PFA relays does not match
with Interlock configuration, when 8123 PFA ENABLE is active. Check consistency of RELAY
OUTPUT parameters 1401 through 1403, and 1410 through 1412. Check 8117 NR OF AUX
MOTORS, 8118 AUTOCHANGE INTERV, and 8120 INTERLOCKS.
Parameter values are inconsistent. Check that parameter 1301 AI MIN > 1302 AI 1 MAX and
that parameter 1304 AI 2 MIN > 1305 AI 2 MAX.
Parameter values are inconsistent. Check that parameter 1504 AO 1 MIN > 1505 AO 1 MAX
and that parameter 1510 AO 2 MIN > 1511 AO 2 MAX.
Parameter values for power control are inconsistent: Improper motor nominal kVA or motor
nominal power. Check the following parameters:
1.1 < (9906 MOTOR NOM CURR * 9905 MOTOR NOM VOLT * 1.73 / PN) < 2.6
Where: PN = 1000 * 9909 MOTOR NOM POWER (if units are kW) or PN = 746 * 9909
MOTOR NOM POWER (if units are HP, e.g., in U.S.A.)
Parameter values are inconsistent. Check the extension relay module for connection and
1410 through 1412 RELAY OUTPUTS 4 through 6 have non-zero values.
Parameter values are inconsistent. Check that a parameter is set for field bus control (e.g.,
1001 EXT1 COMMANDS = 10 (COMM)), but 9802 COMM PROT SEL = 0.
Parameter values are inconsistent. The 9904 MOTOR CTRL MODE must be = 3 (SCALAR
SPEED), when 8123 PFA ENABLE is activated.
Parameter values for power control are inconsistent or improper motor nominal frequency or
speed. Check for both of the following:
1 < (60 * 9907 MOTOR NOM FREQ / 9908 MOTOR NOM SPEED < 16 0.8 < 9908 MOTOR
NOM SPEED / (120 * 9907 MOTOR NOM FREQ / Motor poles) < 0.992
Override mode is enabled and PFA is activated at the same time. This cannot be done
because PFA interlocks cannot be observed in the override mode.
