Trips & Fault Finding
AC30V series Variable Speed Drive
ID Trip Name Possible Reason for Trip
8
INVERSE TIME
A prolonged overload condition, exceeding the Inverse Time allowance, has caused the trip:

Remove the overload condition
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%
10
LOW SPEED I
The motor is drawing too much current (>100%) at zero output frequency:
 FIXED BOOST level set too high
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
12
INTERNAL OVERTEMP
Processor temperature or ambient temperature within the power stage too high

The ambient temperature in the drive is too high
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
14
EXTERNAL TRIP
The external (application) trip input is high:
 Refer to the application description to identify the source of the signal
15
BRAKE SHORT CCT
External dynamic brake resistor has been overloaded:

The external dynamic brake has developed a short circuit.

Wiring fault
16
BRAKE RESISTOR
External dynamic brake resistor has been overloaded:
 Trying to decelerate a large inertia too quickly or too often
17
BRAKE SWITCH
Internal dynamic braking switch has been overloaded:

Trying to decelerate a large inertia too quickly or too often
18
LOCAL CONTROL
Keypad has been disconnected from drive whilst drive is running in Local Control:

GKP accidentally disconnected from drive
