Troubleshooting 4-5
Hardware Fault 130
➁
A non-resettable hardware error has occurred. Cycle power to the drive. If the problem persists,
replace the Control board.
Heatsink OvrTemp 8
➁
The heatsink temperature is too high
Possible causes include:
•
The surrounding air temperature is too high. Lower the surrounding air temperature.
•
The drive’s cooling fans have failed (drives >
110 A). Check the fan fuses and fans. If the fan fuses have
failed, replace the fuses. The fans have failed, replace
the fans.
•
The heatsink is dirty. Clean the heatsink.
Interrupt Error 131
➁
A non-resettable software error has occurred in
the main application. Report this error to the manufacturer.
Inverting Fault 37
➁
A digital input (Pars 133-144) configured as 64
“Invert Flt” has been asserted. Check the status of the inverting fault device connected
to the digital input.
Main Contactor 10
➁
One of the following has occurred:
•
The Main and/or Dynamic Brake (DB)
contactor failed to open or close in the proper
amount of time.
•
A digital input and/or relay output 1 is
incorrectly wired and/or configured.
•
Wiring to a digital input configured for contactor
has opened.
•
Check all contactor wiring and drive jumpers. Repair
or replace the contactor(s) if the problem(s) persist.
•
Check the digital input and/or relay output 1
(terminals 35 and 36) wiring and configuration using
Pars
1391 [ContactorControl], 1392 [Relay Out 1
Sel] and [Digital Inx Sel]. Refer to Using
Contactors on page 1-9 for more information.
Motor Over Temp 16
➀
The motor has exceeded its temperature rating
(as signaled by the thermistor connected to the
drive terminals 78 and 79). Possible causes
include:
•
The motor does not have a thermistor and
there is no resistor between terminals 78 and
79 on the drive. Refer to Thermistors and Thermal Switches on
page 1-25 for configuration information.
•
The cable between the thermistor connection
on the motor and terminals 78 and 79 on the
drive has been broken. Check and repair any damage to or loss of connection
of the thermistor cables between the motor and drive.
•
The overheating of the motor may have been
caused by one of the following:
•
The Load cycle is too extreme.
•
The surrounding air temperature at the site
of motor is too high.
•
The motor has an external fan and the fan
failed.
•
The motor does not have an external fan and
the load is too large at low speeds. The
cooling effect of the internal fan on the motor
shaft is too low for this load cycle.
Reduce the load.
Reduce the surrounding air temperature.
Replace the motor fan.
Reduce the load cycle or fit the motor with an external
fan.
Note: Configure with Par 365 [OverTemp Flt Cfg].
No Fault 0 – There are currently no faults in the drive. Informational only.
Overcurrent 13
➀
An overcurrent has occurred in the motor circuit.
Possible causes include:
•
There is a short-circuit or ground fault at the
output of the drive. Verify the armature circuit wiring is correct.
•
The current regulator was not properly fine
tuned. Refer to Tune the Current Regulator: on page 2-10 .
•
The value of Par 584 [OverCurrent Thr] is too
low.
Increase the value of Par 584 [OverCurrent Thr]
accordingly.
Overspeed 25
➁
The Encoder/Tachometer feedback indicated a
speed that is more than 10% above the value in
Par
2 [Maximum Speed].
Remove the excessive load or overhauling conditions
or increase the value of Par
2 [Maximum Speed].
Params Defaulted 48
➁
User parameters have been reset to their default
values. Informational only.
Port 1-5 Adapter 71 - 75
➁
The communications card has a fault. Check the DPI device event queue and corresponding
fault information for the device.
