DO NOT
attempt to repair a faulty drive.
DO NOT
carry out fault diagnosis other than through the
diagnostic features described in this chapter. A faulty drive must be returned to Nidec for repair.
This section details only main trips of the drive. For the complete list of the trips and their explanations,
refer to http://www.leroy-somer.com/documentation_pdf/5512_en.pdf
If the drive trips on a fault or is in alarm state, a keypad option or “Connect” tool software is needed to
view which trip/alarm code it is.
6.1 Trip Descriptions
If a keypad option is connected to the drive, press the Stop/Reset (Red) button. The fault can also
be cleared (reset) by switching off the ID300/302, or by opening/closing the contact of Terminal 8-DI2
(ID300) or Terminals 31-STO1 & 34-STO2 (ID302).
Note:
The table below provides the most common trips. For a comprehensive list, refer to http://www.

Trip Code
Condition
Description
An Input 1 Loss
Analog input 1 current loss
Current loss was detected in current mode on Analog input 1
(Terminal 2).
An Input 1 OI
Analog input 1 over-current
Current input on analog input 1 exceeds 24 mA.
An Input 2 Loss
Analog input 2 current loss
Current loss was detected in current mode on Analog input 2
(Terminal 4).
An Input 2 OI
Analog input 2 over-current
Current input on analog input 2 exceeds 24 mA.
An Input 3 Loss
Analog input 3 current loss
Current loss was detected in current mode on Analog input 3
(Terminal 5).
An Input 3 OI
Analog input 3 over-current
Current input on analog input 3 exceeds 24 mA.
Autotune
Measured inertia has exceeded
the parameter range
The drive has tripped during a rotating autotune or mechanical
load measurement test.
Autotune Stopped
Autotune test stopped before
completion
The drive was prevented from completing an autotune test,
because either the drive enable or the drive run signals were
removed.
Destination
Two or more parameters are
writing to the same destination
parameter
This trip indicates that destination output parameters of two or
more logic functions (Menus 7 to 9, 12 or 14) within the drive
are writing to the same parameter.
External Trip
External trip is initiated
The cause of the trip can be identified from the sub trip
number displayed after the trip string.
I/O Overload
Digital output overload
The total current drawn from 24 V user supply or from the
digital output has exceeded the limit.
Keypad Mode
Remote keypad has been
removed when the drive is
receiving the reference from the
keypad
This trip indicates that the drive is in keypad mode and the
keypad has been removed or disconnected from the drive.
