11. Failures signalization
When an operational failure or a parameter set manipulation error occures, the
corresponding error code is signalized on the display as a flashing message „
Er.NN
“,
where NN is the numeric error identifier.
11.1. Operational
failures
Er.00
- internal protection inverter shut-down
cause: short circuit, overcurrent, Ixt, overvoltage, undervoltage, damaged
motor, motor or power supply connection failure, motor windings
connection failure
solution: Find out the cause, clear the fault, restart the drive.
Note: A strong interference source near the inverter can cause an
accidental shut-down of the inverter. In this case the interference
source should be removed, eliminated or suppressed using
electromagnetic screen, noise suppressor or any other suitable
interference suppressor or combination of them.
Er.01
- inverter shut-down caused by an invalid input analogue signal during
remote control
cause: The invalid input signal or incorrect parameter CINP setting
solution: Find out the cause, clear the fault, restart the drive.
Er.02
- communication error between inverter and control pod
cause: Connection failure, too long cable, strong interference near the
cable
solution: Quit the failure signalization by pressing any of the keys UP,
DOWN, PAR. If the communication failure repeats, check the
cable and its connection to the drive. If the failure still repeats, try
to find out and eliminate the interference source, or reduce the
cable length.
Er.03
- software incompatibility
cause: The software versions of the inverter and control pod are
incompatible
solution: se the control pod with a compatible software version.
11.2.
Parameter sets manipulation errors
Er.10 - Er.17
- EEPROM read/write failure
cause: Accidental or repeated hardware failure
solution: If the failure occures accidentaly, you can quit the
signalization by pressing any of the keys PAR, UP, DOWN,
STOP. If not accidental, the hardware failure requires the
service reparation.
WARNING ! If this failure occures during READ operation (loading the
working area), it is necessary to repeat the READ operation as
the working area may contain incorrect data. The RUN
command must not be executed before correct data has been
loaded into the working area.
Er.18
- unusable data in the selected parameter set
cause: The set is empty (not yet programmed) or incompatible data format
was recognized (such set can be also assumed as an empty set)
solution: Quit the signalization and load (READ) another parameter set.
