Diagnostics and troubleshooting
S1A53838 09/2011 151
Err2
[RAM fault]
The control board RAM is inoperable. Contact Schneider Electric to repair the
drive.
Err3
[ROM fault]
The control board ROM is inoperable. Contact Schneider Electric to repair the
drive.
Err4
[CPU fault 1]
The control board CPU is inoperable. Contact Schneider Electric to repair the
drive.
Err5
[Com RJ45 fault]
Serial communication error Check network control devices and cables.
Check the setting of the communication
timeout parameter, F803.
Check the remote graphic display option
cable.
Check the setting of F829 parameters.
Err7
[Current sensor fault]
A motor current sensor is inoperable. Replace the drive.
Err8
[Network error fault]
Network communication error Check the network control devices and
cables.
Err9
[Remote keypad
fault]
Graphic display option cable disconnected Check the RJ45 cable.
Etn1
[Auto-tuning fault]
Parameters F401 to F494 are
incorrectly set.
The motor is too large for the drive.
The motor cable gauge is too small.
The motor is still rotating at the start of the
auto-tune.
The drive is not powering a 3-phase
induction motor.
Set parameters F401F494 correctly.
Use a larger drive.
Use a larger gauge motor cable.
Verify that the motor is stopped before
starting an auto-tune.
Use the drive to power only a 3-phase
induction motor.
EtYP
[Drive fault]
The main control board is inoperable. Set parameter [Parameter reset] (tYP) to
6.
If this does not clear the detected error,
replace the drive.
Fd1
[Closed damper 1
fault]
Damper is locked in closed position. Set [Damper flt behavior] (F583) to 0.
Check the FL relay connection (FLA/FLB).
Check the relay configuration
(
F130/F132).
Fd2
[Closed damper 2
fault]
Damper blocked open or soldered. Set [Damper fdb type] (F580) to 0 or
1.Check the FL relay connection
(
FLA/FLB).
Check the relay configuration
(
F130/F132).
M020
[Total input power]
The accumulated input power value is more
than 999.999 kWh.
Clear the accumulated input power value
using logic input function 51, or parameter
F748.
OC1
[Overcurrent
acceleration]
The acceleration time is too short.
The setting of parameter [Mot cont. mode
sel.] (Pt) is incorrect.
The drive is starting into a rotating load.
The drive is powering a low impedance
motor.
Ground fault
Increase the acceleration time parameters
(ACC or F500).
Select the correct setting for parameter [Mot
cont. mode sel.] (Pt).
Enable catch on the fly, parameter F301.
Adjust the switching frequency parameter
F300.
Set parameter F316 to 1 or 3.
OC1P
[SC or ground fault
acc.]
Short circuit or ground fault during
acceleration
Using a 1000 V testing tool megger, check
the motor and motor cables for ground faults.
OC2
[Overcurrent
deceleration]
The deceleration time is too short.
Ground fault
Increase the deceleration time parameters
(dEC or F501).
Set parameter F316 to 1 or 3.
OC2P
[SC or ground fault
dec.]
Short circuit or ground fault during
deceleration
Using a 1000 V megger, check the motor and
motor cables for ground faults.
OC3
[Overcurrent cont.
speed]
Abrupt fluctuations in load
Abnormal load condition
Reduce the load fluctuations.
Check the load.
Set parameter F316 to 1 or 3.
OC3P
[SC/ground flt cont.
spd]
Short circuit or ground fault during constant
speed operation
Using a 1000 V megger, check the motor and
motor cables for ground faults.
OCA
[SC inverter at start]
Ground fault Using a 1000 V megger, check the motor and
motor cables for ground faults.
OCL
[SC mot. cable at
start]
Phase to phase output short circuit
The motor impedance is too low.
Using a 1000 V megger, check the motor and
motor cables for ground faults.
