Correcting Alarms
To correct alarms, first determine if the alarm requires any correc-
tive action (corrective action is not always required). Use
Table AH to find and address the root cause of the problem.
If diagnostics troubleshooting has determined that the drive is de-
fective during the warranty period, contact Carrier.
Control Panel Cleaning
Use a soft damp cloth to clean the control panel. Avoid harsh
cleaners which could scratch the display window.
APPENDIX D — VFD INFORMATION (CONT)
Table AH — FAULT AND ALARM CODES for ACH580 VFD (cont)
Start interlock 3 is keeping the drive from
starting.
Start interlock 4 is keeping the drive from
starting.
A forced DI is used as a source for
parameter 20.40 Run permissive.
One or more forced DIs is used as a
source for one or more of parameters
20.41 Start interlock 1 ... 20.44 Start
interlock 4.
The Safe torque off function was active
and has been reset while in Override.
Motor ID run will occur at next start.
Preheating is being performed
Drive is in Override mode.
The drive was powered up or the control
board was rebooted successfully.
The drive was placed in Hand mode.
The drive was placed in Off mode.
The drive was placed in Auto mode.
Output current has exceeded internal
fault limit.
In addition to an actual overcurrent
situation, this fault may also be caused by
an earth fault or supply phase loss.
Motor ID run was not completed
successfully.
CAUSE
Check the signal source selected for parameter 20.43 Start interlock 3.
Check the signal source selected for parameter 20.44 Start interlock 4.
If 20.40 Run permissive uses DIx as the source, check if the bit
corresponding to DIx in parameter 10.03 DI force selection is 1.
Check all parameters 20.41 Start interlock 1 ... 20.44 Start interlock 4. If
any of these parameters uses DIx as the source, check if the bit
corresponding to DIx in parameter 10.03 DI force selection is 1.
A new start signal is required to start the drive again.
Informative warning.
Informative warning.
Motor preheating is active. Current specified by parameter 21.16
Preheating current is being passed through the motor.
Informative warning.
Informative event.
Informative event. Check the control panel to ensure that the current
control location is correct.
Informative event. Check the control panel to ensure that the current
control location is correct.
Informative event. Check the control panel to ensure that the current
control location is correct.
Check motor load.
Check acceleration times in parameter group 23 Speed reference ramp
(speed control) or 28 Frequency reference chain (frequency control).
Also check parameters 46.01 Speed scaling, 46.02 Frequency scaling
and 46.03 Torque scaling.
Check motor and motor cable (including phasing and delta/star
connection). Check there are no contactors opening and closing in
motor cable.
Check that the start-up data in parameter group 99 corresponds to the
motor rating plate.
Check that there are no power factor correction capacitors or surge
absorbers in motor cable.
Check for an earth fault in motor or motor cables by measuring the
insulation resistances of motor and motor cable. See chapter Electrical
installation, section Checking the insulation of the assembly in the
Hardware manual of the drive.
Check safety circuit connections. For more information, see chapter The
Safe torque off function in the Hardware manual of the drive and
description of parameter 31.22 STO indication run/stop(page 520).
Check the value of parameter 95.04 Control board supply.
Check the nominal motor values in parameter group 99 Motor data.
Check that no external control system is connected to the drive.
Cycle the power to the drive (and its control unit, if powered separately).
Check that no operation limits prevent the completion of the ID run.
Restore parameters to default settings and try again.
Check that the motor shaft is not locked. Check the auxiliary code.
Battery Replacement
A battery is only used in assistant control panels that have the
clock function available and enabled. The battery keeps the clock
operating in memory during power interruptions. The expected
life for the battery is greater than ten years. To remove the battery,
use a coin to rotate the battery holder on the back of the control
panel. Replace the battery with type CR2032.
