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.

Trips and Fault Finding
Possible Reason for Trip
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
DC link low trip:
Supply is too low/power down
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
External dynamic brake resistor has been overloaded:
 Trying to decelerate a large inertia too quickly or too
often
Internal dynamic braking switch has been overloaded:

Trying to decelerate a large inertia too quickly or too
often
