Table 53 continued: Fault Listing
Fault Code
Fault Name In Panel
Description and Recommended Corrective Action
16
EARTH FAULT
Possible ground fault detected in the motor or motor cables . The drive monitors for ground faults while the drive is
running and while the drive is not running . Detection is more sensitive when the drive is not running and can produce
false positives .
Possible corrections:
• Check for/correct faults in the input wiring .
• Verify that motor cable does not exceed maximum specified length.
• A delta grounded input power supply and motor cables with high capacitance may result in erroneous error reports
during non-running tests . To disable response to fault monitoring when the drive is not running, use parameter 3023
WIRING FAULT . To disable response to all ground fault monitoring, use parameter 3017 EARTH FAULT .
18
THERM FAIL
Internal fault . The thermistor measuring the internal temperature of the drive is open or shorted . Contact your local
Daikin sales representative .
19
OPEX LINK
Internal fault. A communication-related problem has been detected on the fiber optic link between the OITF and OINT
boards . Contact your local Daikin sales representative .
20
OPEX PWR
Internal fault . Low voltage condition detected on OINT power supply . Contact your local Daikin sales representative .
21
CURR MEAS
Internal fault . Current measurement is out of range . Contact your local Daikin sales representative .
22
SUPPLY PHASE
Ripple voltage in the DC link is too high . Check for and correct:
• Missing mains phase .
• Blown fuse .
23
ENCODER ERR
The drive is not detecting a valid encoder signal . Check for and correct:
• Encoder presence and proper connection (reverse wired, loose connection, or short circuit) .
• Voltage logic levels are outside of the specified range.
• A working and properly connected Pulse Encoder Interface Module, OTAC-01 .
24
OVERSPEED
Motor speed is greater than 120% of the larger (in magnitude) of 2001 MINIMUM SPEED or 2002 MAXIMUM SPEED .
These are factory set and tested . Contact your local Daikin sales representative if there is a problem .
Check for and correct:
• Adequacy of motor braking torque .
• Applicability of torque control .
• Brake chopper and resistor .
25
RESERVED
Not used as of the publication of this manual .
26
DRIVE ID
Internal fault. Configuration Block Drive ID is not valid. Contact your local Daikin sales representative.
27
CONFIG FILE
Internal configuration file has an error. Contact your local Daikin sales representative.
28
SERIAL 1 ERR
Fieldbus communication has timed out . Check for and correct:
• Fault setup (3018 COMM FAULT FUNC and 3019 COMM FAULT TIME) .
• Communication settings (Group 51 or 53 as appropriate) .
• Poor connections and/or noise on line .
29
EFB CONFIG FILE
Error in reading the configuration file for the embedded fieldbus.
30
FORCE TRIP
Fault trip forced by the fieldbus. See the fieldbus User’s Manual.
31
EFB 1
Fault code reserved for the embedded fieldbus (EFB) protocol application. These codes are not used as of the
publication of this manual .
32
EFB 2
33
EFB 3
34
MOTOR PHASE
Fault in the motor circuit . One of the motor phases is lost . Check for and correct:
• Motor fault .
• Motor cable fault .
• Thermal relay fault (if used) .
• Internal fault .
35
OUTPUT WIRING
Possible power wiring error detected . When the drive is not running it monitors for an improper connection between the
drive input power and the drive output . Check for and correct:
• Proper input wiring – line voltageis NOT connected to drive output .
• The fault can be erroneously declared if the input power is a delta grounded system and motor cable capacitance is
large .
36
INCOMP SWTYPE
The drive cannot use the software .
• Internal Fault .
• The loaded software is not compatible with the drive . • Call support representative .
37
CB OVERTEMP
Drive control board is overheated .
Check for and correct:
• Excessive ambient temperatures
• Fan failure .
• Obstructions in the air flow.
