Possible Reason for Trip
Keypad has been disconnected from drive whilst drive is
running in Local Control:

Keypad accidentally disconnected from drive (indicated
over Comms, or by second keypad)
Lost communications:

COMMS TIMEOUT parameter set too short

Master device failed

Wiring broken
 Incorrect Comms setup
Contactor feedback signal lost:

Check connection to the terminal wired to "contactor
closed" parameter in Sequencing Logic (non-standard
configuration)
Speed feedback:
 SPEED ERROR > 50.00% for 10 seconds
Ambient temperature:
 The ambient temperature in the drive is too high
The motor temperature is too high:

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
Software overcurrent trip:

If the current exceeds 180% of stack rated current for a
period of 1 second, the drive will trip. This is caused by
shock loads. Remove the shock load.

ACCEL TIME and/or FIXED BOOSTset too high

DECEL TIME set too low
The motor is drawing too much current (>100%) at zero
output frequency:

FIXED BOOST level set too high
10V fault:
 +10V REF overload warning (terminal 4) -
10mA maximum
The dc link ripple voltage is too high:
 Check for a missing input phase
Overspeed:

>150% base speed when in Sensorless Vector mode
AOUT overload on terminal 5:

10mA maximum
DIN3 overload on terminal 9:
 20mA maximum
