Chapter 5 - Troubleshooting & Maintenance
1 - ERRORS
1.1 - "SYSTEM" ERROR
If the red "SYS" LED is lit at power on, the logic board is defective.
•
Check that the
BUS
and
OK
leds are synchronously blinking. In this case, load the amplifier firmware via the
serial link by means of the
CD1updater software
.
•
Check for no conducting dust that may involve short-circuits on the amplifier logic board.
1.2 - NON STORED ERRORS
1.2.1 - BUS ERROR
This fault is displayed by the
BUS
led.
This error is only displayed when there is a synchronization loss by the
SYNC
message.
The error is cancelled as soon as the communication is restored.
1.2.2 - "UNDERVOLT." ERROR
This fault is displayed by a quick blinking of the
OK
led.
When switching on the auxiliary 24 V
DC
supply, the CD1-k amplifier always displays the UNDERVOLT. fault. The
UNDERVOLT. Led will go out when switching on the power voltage, after a few seconds time delay that
corresponds to the power capacitors soft start. If the fault display remains after switching on the power supply,
check that the power supply is actually on.
1.3 - STORED ERRORS
If an error occurs on the amplifier, it can generate the detection of several other errors which are only a
consequence of the initial one. In order to make diagnostic and maintenance easier, the errors are displayed and
processed with the precedence described below. For safety reasons, the power must be turned off for the
cancelling of some errors that requires the handling of the amplifier; in this case, the amplifier is automatically
reset when power is turned on again. If power is not turned off, do not forget to make a RESET immediately after
the error is cancelled.
1.3.1 - "BUSY" ERROR
•
If
the
BUSY
error is displayed after power on, the AUTOTEST procedure has failed and the amplifier is not
ready for operation.
Check that the power voltage is not on before the 24 V auxiliary supply
.
•
If the BUSY fault is continuously displayed after the motor
PHASING
procedure at power up (
Incremental
encoder
without HES
configuration), the procedure has failed because of an external cause and the
calculated phase value is wrong.
Check that the
Motor encoder resolution
parameter value is correct.
Check that the
Motor parameters
(
Pole pairs
and
Phase order
) values are correct.
Check that the
INHIBIT
input is disabled.
Check that the limit switches inputs are not activated.
Check that the motor is not locked and the shaft movement is free during the procedure.
•
If
the
BUSY
error is displayed after execution of the
Autophasing
, this procedure has failed because of an
external cause and the calculated parameters are wrong.
Check at first the status of the amplifier logic inputs. Check that the motor is unloaded and the shaft movement
is free during the procedure.
