Appendix B Diagnostics
Users must not attempt to repair a Drive if it is faulty,
nor carry out fault diagnosis other than through the
use of the diagnostic features described in this
Appendix.
Under no circumstances must the casing of the Drive
be opened when the AC supply is connected.
If a Drive is faulty, it must be returned to an authorised
Control Techniques distributor for repair.
B.1 Types of indications
Status indications
Version _ AN : When the Drive is in normal operation and the display is in
Status mode, its lower line shows a code which indicates the status of
the Drive.
Both versions, especially version _
SL : Parameters that are used for
indicating status can be read via serial communications.
Alarm indications
Version _ AN : If a critical condition is detected, the Drive continues
operating. When the display is in Status mode, its lower line shows an
alarm code in place of the status code. If the condition is not rectified, the
Drive could trip.
The alarm message flashes alternately with the normal display
indication.
Both versions, especially version _
SL : Parameters that are used for
indicating alarms can be read via serial communications.
Trip codes
Version _ AN : If the Drive trips, the output is disabled so that the Drive
stops controlling the motor. When the display is in Status mode, its
lower line indicates that a trip has occurred and the upper line shows a
trip code.
Both versions, especially version _
SL : Each trip code has a
corresponding numerical value which is entered into parameter 10.20 .
This can be read via serial communications.
B.2 Status indications
Lower line of the display
The number given in brackets under each status indication is the number
of the parameter that is correspondingly set at
1 . After Standard Security
has been unlocked, these parameters can be read via serial
communications.
B.3 Status LEDs
When illuminated, these indicate the following:
When the state of any of these LEDs indicates that the Drive has tripped,
perform the following:
Version _
AN : Read the trip code displayed on the upper line of the
alphanumeric display and refer to on page 84.
Both versions, especially version _
SL : Read the value of parameter
10.20 via serial communications and refer to on page 84.
B.4 Alarm indications
Version _AN
Alarm indications appear on the lower line of the display.
Version _SL
The number given in brackets under each alarm indication (in the
following list) is the number of the parameter that is correspondingly set
at
1 . To identify which alarm has ocurred, check the settings of these
parameters via serial communications.
Global alarm indication
When an alarm occurs, parameter 10.19 becomes set at 1 .
inh
[0.01 set
at 0]

Hardware enable signal is applied.
RUN contact is open.
The Drive output is enabled.
The motor is stopped (speed reference is zero).
run
[10.02
set at 1]
Hardware enable signal is applied.
RUN contact is closed.
Motor is accelerating or at a steady speed.
Jo9
[1.13 set
at 1]
Hardware enable signal is applied.
JOG FORWARD contact is closed.
Ini
Servo initialisation at power-up and when the Drive
is reset.
CSP [6.49]
The motor is being subject to controlled
deceleration to a stop during failure of the AC
supply
WARNING
SbY
[6.44 set
at 1]
The Drive and SLM are being supplied from an
auxiliary back-up supply.
dEC The motor is being decelerated by the Drive
trP
[10.01
set at 0]
The Drive has tripped and is no longer controlling
the motor.
The trip code appears on the upper line of the
display. See Trip codes on page 85.
The Drive output is disabled allowing the motor to
coast.
D1 red
Trip OI.AC has occurred; control of the motor
has ceased
D2 red
The Drive has tripped due to a cause other
than OI.AC; control of the motor has ceased
D3 green
The Drive is operating normally (Drive
healthy); when unlit, this indicates the Drive
has tripped
D4 amber
The Drive is enabled, allowing the motor to
be driven
Ibr [10.12]
The [I
2
t] accumulator for the internal braking resistor in
the Drive has reached 75% of the value at which the
Drive will be tripped.
The Drive output remains enabled.
OuL [10.17]
The motor thermal-overload accumulator in the Drive
indicates that the motor windings are at their maximum
specified working temperature (see Adjusting the
threshold for the motor thermal-overload alarm on page
105).
The Drive output remains enabled.
If the motor current is not reduced, the Drive will trip
(trip code:
I2t.AC ).
hot [10.18]
The Drive heatsink and/or internal control circuits have
reached 90°C (176°F).
