USING THE KEYPAD TO MANAGE TRIPS
Trip Messages
If the drive trips, then the display immediately shows a message indicating the reason for the trip. The possible trip messages are given in the
table below.
ID
Trip Name
Possible Reason for Trip
Criteria for Warning
1
OVER VOLTAGE
The drive internal dc link voltage is too high:
 The supply voltage is too high
 Trying to decelerate a large inertia load too quickly; DECEL TIME time too short
The brake resistor is open circuit
To help prevent this trip, enable the DC Link Volts Limit feature
Internal dc link voltage has
reached midway between the
over voltage trip level and the
dynamic braking resistor control
voltage.
2
UNDER VOLTAGE
DC link low trip:
 Supply is too low/power down
Internal dc link voltage has
reached midway between the
lowest expected instantaneous
voltage and the under voltage
trip level.
3
OVER CURRENT
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
The over current trip makes up
of a multiple-attempt strategy.
The warning is triggered if two
or more consecutive overcurrent
events are encountered (whereas
five consecutive events are
required for a Trip to occur).
4
STACK FAULT
Stack self protection
 Instantaneous overcurrent detected by the power stack. Refer to OVERCURRENT in
this table.
 Instantaneous over voltage event. Refer to OVER VOLTAGE in this table
Not applicable.
5
STACK OVER
CURRENT
The motor current exceeded the capabilities of the power stack.
 Instantaneous overcurrent detected by the power stack. Refer to OVERCURRENT in
this table.
Not applicable.
6
CURRENT LIMIT
V/Hz mode only: If the current exceeds 200% of stack rated current for a period of
1 second, the drive will trip. This is caused by shock loads
Not applicable.
