DIAGNOSTICS
Trip code
Condition
Description
Over Volts
DC bus voltage has exceeded the
peak level or maximum continuous
level for 15 seconds
This trip indicates that the DC bus voltage has
exceeded the maximum limit. Possible solutions:
• Increase Deceleration Rate (Pr
00.004)
,
• Check nominal AC supply level,
• Check for supply disturbances which could cause the
DC bus to rise,
• Check motor insulation using a insulation tester.
Phase Loss
Supply phase loss
The drive has detected an input phase loss or large
supply imbalance.
Th Brake Res
Brake resistor over temperature
This trip is initiated if the hardware based braking
resistor thermal monitoring is connected and the
resistor overheats.
Thermistor
Motor thermistor over-temperature
The Thermistor trip indicates that the motor thermistor
connected to terminal 4 (ADI2) on the control connec-
tions has indicated a motor over temperature.

Alarm descriptions
In any mode, an alarm is an indication given from the flashing red LED of the flange option or on the keypad display
by alternating the alarm string with the drive status string display. If an action is not taken to eliminate any alarm
except “Auto Tune” and “Limit Switch”, the drive may eventually trip. Alarms are not displayed when a parameter is
being edited.
Alarm string
Description
Brake Resistor
Brake resistor overload. Braking Resistor Thermal Accumulator (Pr
10.039
) in the
drive has reached 75.0 % of the value at which the drive will trip
Motor Overload
Motor Protection Accumulator (
04.019
) in the drive has reached 75.0 % of the value at
which the drive will trip and the load on the drive is >100 %.
Drive overload
Drive over temperature. Percentage Of Drive Thermal Trip Level (Pr
07.036
) in the
drive is greater than 90 %.
Auto Tune
The autotune procedure has been initialized and an autotune is in progress.
Limit Switch
Limit switch active. Indicates that a limit switch is active and that is causing the motor
to be stopped.
Option Slot 1
Option slot alarm.
Low AC
Low voltage mode. See low AC alarm (Pr 1
0.107
).
Current Limit
Current limit active. See Current Limit Active (
10.009
).
Fan
Fan reversed or failed.
