Description
Possible Reason for Trip
OVERVOLTAGE
The drive internal dc link
voltage is too high
The supply voltage is too high
Trying to decelerate a large inertia load too quickly
The brake resistor is open circuit
UNDERVOLTAGE
The drive internal dc link
voltage is too low
The supply voltage is too low
The supply has been lost
A supply phase is missing
OVERCURRENT
The motor current being
drawn from the drive is
too high
Trying to accelerate a large inertia load too quickly
Trying to decelerate a large inertia load too quickly
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 or auto boost levels are set too high
HEATSINK
The drive heatsink
temperature is too high
The ambient air temperature is too high
Poor ventilation or spacing between drives
EXTERNAL TRIP
User trip caused via
control terminals
+24V not present on external trip (terminal X15/05)
Check setting of EXT TRIP MODE parameter
INPUT 1 BREAK
I/O TRIPS:: INPUT 1
BREAK has gone True
Check configuration to determine source of signal
