Trip descriptions
The fault can be cleared (reset) by switching off the Commander ID300/302 or by opening/closing the contact of
terminal 8-DI2 (ID300) or terminals 31-STO1 & 34-STO2 (ID302). If a keypad option is connected to the drive,
press the Stop/reset (red) button.
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.
Brake R Too
Hot
Braking resistor overload timed out
(I
2
t)
Braking resistor overload has timed out.
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 and 8) 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. Refer to drive
user and technical guide ref.5512.
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.
Motor Too Hot
Output current overload timed
out (I
2
t)
This trip indicates a motor thermal overload based on
the output current and motor thermal time constant. The
drive will trip on Motor Too Hot when the accumulator
gets to 100 %. This can occur when:
• There is excessive mechanical load, ensure the load
is not jammed / sticking,
• Check the load on the motor has not changed,
• Ensure the motor rated current is not zero.
OHt Brake
Braking IGBT over-temperature
Braking IGBT over-temperature
OI ac
Instantaneous output over current
detected
The instantaneous drive output current has exceeded
the set limit. Possible explanations:
• acceleration/deceleration rate too low,
• If seen during autotune voltage boost too low,
• Possible short circuit on the output cabling,
• Possible integrity issue of the motor insulation,
• values in the current loop gain parameters too high.
Over Speed
Motor frequency has exceeded the
over frequency threshold
Excessive motor speed (typically caused by mechanical
load driving the motor).
