Trips and Fault Finding
Possible Reason for Trip
The motor current being drawn from the drive is too high:
• Trying to accelerate a large inertia load too quickly;
ACCEL TIME time too short
•
Trying to decelerate a large inertia load too quickly;
DECEL TIME time too short
• Application of shock load to motor
•
Short circuit between motor phases
•
Short circuit between motor phase and earth
• Motor output cables too long or too many parallel
motors connected to the drive
•
FIXED BOOST level set too high
Drive heatsink temperature > 100ºC:
•
The ambient air temperature is too high
Poor ventilation or spacing between drives
The external trip input is high:
•
Check configuration to identify the source of the signal
(non-standard configuration)
A prolonged overload condition, exceeding the Inverse Time
allowance, has caused the trip:
•
Remove the overload condition - refer to Chapter 5:
A current of less than 1mA is present when 4-20mA setpoint
is selected:
•
Look for a wire break
The motor has stalled (not rotating) Drive in current limit
>200 seconds:
• Motor loading too great
•
FIXED BOOST level set too high
AIN2 overload on terminal 3:
• Overcurrent applied in Current mode to terminal 3
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)
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
