Detected fault conditions
Refer to tables on pages hereafter to diagnose and solve troubles when there is a fault detection, or when an
alarm, or pre-alarm condition occurs.
If the trouble cannot be solved by the actions described in the tables, contact your Schneider Electric
representative.
Alarm Codes
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
• Read and understand the instructions in «Before you begin» chapter, before performing the procedure in
this section.
Failure to follow these instructions will result in death or serious injury.
Code Name Possible causes Remedies
CFI2
[Download transfer
fault]
• Invalid configuration.
The configuration loaded in the drive via the
bus or communication network is
inconsistent.
• Transfer using PC soft has not been
successful due to rating differences
(for example upload of an ATV212pppN4
configuration to an ATV212pppM3)
• Check the configuration loaded previously.
• Load a compatible configuration.
• To perform download, uncheck "Display
communication error" (in Tool /
Environnement option / Startup/Comm.)
E-18
[VIA signal fault]
• The VIA analog signal is below the level set
by parameter F633.
• Check the signal at VIA and rectify the cause
of the signal loss.
• Verify that parameter F633 is set
correctly.
E-19
[CPU communica-
tions err.]
• Communication error between control CPUs • Contact Schneider Electric to repair the
drive.
E-20
[Excess torque boost
flt]
• Torque boost parameter
[Auto Torque Boost] (F402) is set too
high.
• The motor impedance is too low.
• Repeat the drive auto-tune and then adjust
down parameter [Auto Torque Boost]
(F402).
During deceleration when
[Mot cont. mode sel.] (Pt) = (1) [Quadr. U/F]
with 3 conditions:
- Processing for stop
- Load current value > 88% x [Motor Current
Limitation] (F601)
- Too slow deceleration, [Max frequency]
(FH) /[Deceleration time 1] (dEC) x 2 msec
< 0.01Hz
• Set [Auto ramp] (AU1) = (0) [Disabled]
• Decrease the deceleration ramp with
[Deceleration time 2] (F501) and
[Commut. ramp freq.] (F505).
E-21
[CPU error 2 fault]
• The control board CPU is inoperable. • Contact Schneider Electric to repair the
drive.
E38
[EEprom pwr incom-
pat.]
• Eeprom power incompatible.
• Product hardware detected fault.
• Contact Schneider Electric to repair the
drive.
EEP1
[EEPROM error 1
fault]
• A data writing error has occurred. • Cycle power to clear the detected fault.
EEP2
[EEPROM error 2
fault]
• Power was removed from the drive during a
parameter reset operation resulting in a
data writing error.
• Cycle power to clear the detected fault and
try the parameter reset operation again.
• If the detected fault does not clear, contact
Schneider Electric to repair the drive.
EEP3
[EEPROM error 3
fault]
• A data reading error has occurred. • Cycle power to clear the detected fault.
EF2
[Ground fault]
• Ground fault in motor or motor cables • Check the motor and motor cables for
ground faults.
EPHO
[Output phase loss
fault]
• Loss of one or more output phases • Determine the cause of the missing output
phase (such as a bad connection, an output
disconnect, or an open winding in the motor)
and rectify the trouble.
• Check parameter F605.
EPHI
[Input phase loss
fault]
• Loss of one input phase • Determine the cause of the missing input
phase and rectify.
• Check parameter F608.
Err1
[Speed ref. error
fault]
• Parameters F202, F203, F210, or
F212 are set improperly.
• Set the parameters to the correct settings.
