Trips & Fault Finding
10-3
AC30 series Variable Speed Inverter
ID
Trip Name
Possible Reason for Trip
Criteria for Warning
7
MOTOR STALL
The motor has stalled (not rotating) Drive in current limit >200 seconds:
•
Motor loading too great
•
FIXED BOOST level set too high
The stall condition has been
detected for more than one tenth
of the configured Stall Time.
8
INVERSE TIME
A prolonged overload condition, exceeding the Inverse Time allowance, has caused the
trip:
•
Remove the overload condition
An overload condition has
exceeded one half of the Inverse
Time allowance.
9
MOTOR I2T
Only for PMAC Motor: A prolonged load condition, exceeding the motor rated
current, has caused the trip. The estimated motor load has reached a value of 105%
An overload condition has
exceeded one half of the motor
Inverse Time allowance.
10
LOW SPEED I
The motor is drawing too much current (>100%) at zero output frequency:
•
FIXED BOOST level set too high
Not applicable.
11
HEATSINK
OVERTEMP
Drive heatsink temperature too high
•
The ambient air temperature is too high
•
Poor ventilation or spacing between drives
•
Check heatsink fan is rotating
The drive heatsink has exceeded
the warning temperature level
(which is approx. 10
°
C below the
trip temperature).
12
INTERNAL
OVERTEMP
Processor temperature or ambient temperature within the power stage too high
•
The ambient temperature in the drive is too high
The drive processor temperature
has exceeded the warning
temperature level (which is
approx. 10
°
C below the trip
temperature).
13
MOTOR
OVERTEMP
The motor temperature is too high, (required IO Option card)
•
Excessive load
•
Motor voltage rating incorrect
•
FIXED BOOST level set too high
•
Prolonged operation of the motor at low speed without forced cooling
•
Break in motor thermistor connection
The motor has been over
temperature for 7.5 seconds.
14
EXTERNAL TRIP
The external (application) trip input is high:
•
Refer to the application description to identify the source of the signal
Not applicable.
15
BRAKE SHORT
CCT
External dynamic brake resistor has been overloaded:
•
The external dynamic brake has developed a short circuit.
•
Wiring fault
Not applicable.
