APPENDIX C — VARIABLE FREQUENCY DRIVE (VFD) (cont)
Table V — Fault Codes (cont)
FAULT CODE FAULT NAME IN PANEL DESCRIPTION AND RECOMMENDED CORRECTIVE ACTION
20 OPEX PWR Internal fault. Low voltage condition detected on the OINT board. Contact Carrier.
21 CURR MEAS Internal fault. Current measurement is out of range. Contact Carrier.
22 SUPPLY PHASE Ripple voltage in the DC link is too high. Check for missing main phase or blown fuse.
23 RESERVED Not used.
24 OVERSPEED
Motor speed is greater than 120% of the larger (in magnitude) of 2001 MINIMUM SPEED or 2002
MAXIMUM SPEED parameters. Check parameter settings for 2001 and 2002. Check adequacy of
motor braking torque. Check applicability of torque control. Check brake chopper and resistor.
25 RESERVED Not used.
26 DRIVE ID Internal fault. Configuration block drive ID is not valid.
27 CONFIG FILE Internal configuration file has an error. Contact Carrier.
28 SERIAL 1 ERR
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.
29 EFB CON FILE Error in reading the configuration file for the field bus adapter.
30 FORCE TRIP Fault trip forced by the field bus. See the field bus reference literature.
31 EFB 1 Fault code reserved for the EFB protocol application. The meaning is protocol dependent.
32 EFB 2 Fault code reserved for the EFB protocol application. The meaning is protocol dependent.
33 EFB 3 Fault code reserved for the EFB protocol application. The meaning is protocol dependent.
34 MOTOR PHASE
Fault in the motor circuit. One of the motor phases is lost. Check for motor fault, motor cable fault,
thermal relay fault, or internal fault.
35 OUTP WIRING Error in power wiring suspected. Check that input power wired to drive output. Check for ground faults.
101-105 SYSTEM ERROR Error internal to the drive. Contact Carrier and report the error number.
201-206 SYSTEM ERROR Error internal to the drive. Contact Carrier and report the error number.
1000 PAR HZRPM
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/+128
2002 MAXIMUM SPEED / 9908 MOTOR NOM SPEED is outside of the range: -128/+128
2007 MINIMUM FREQ / 9907 MOTOR NOM FREQ is outside of the range: - 128/+128
2008 MAXIMUM FREQ / 9907 MOTOR NOM FREQ is outside of the range: - 128/+128
1001 PAR PFA REFNG
Parameter values are inconsistent. Check that 2007 MINIMUM FREQ is negative, when 8123 PFA
ENABLE is active.
1002 PAR PFA IOCNF
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.
1003 PAR AI SCALE
Parameter values are inconsistent. Check that parameter 1301 AI 1 MIN > 1302 AI 1 MAX and that
parameter 1304 AI 2 MIN > 1305 AI 2 MAX.
1004 PAR AO SCALE
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.
1005 PAR PCU 2
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 US)
1006 PAR EXT RO
Parameter values are inconsistent. Check the extension relay module for connection and 1410 through
1412 RELAY OUTPUTS 4 through 6 have non-zero values.
1007 PAR FBUS
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.
1008 PAR PFA MODE
Parameter values are inconsistent. The 9904 MOTOR CTRL MODE must = 3 (SCALAR SPEED) when
8123 PFA ENABLE activated.
1009 PAR PCU 1
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
1010
OVERRIDE/PFA
CONFLICT
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.
