Possible cause/Suggested solution
Motor overload
The motor has reached its maximum thermal capacity. Overload
can be caused by:
•
The soft starter protection settings not matching the motor
thermal capacity
•
Excessive starts per hour or start duration
•
Excessive current
•
Damage to the motor windings
Resolve the cause of the overload and allow the motor to cool.
Related parameters: 1B, 1C, 1D, 1E, 5G, 6D
NOTE
Parameters 1C, 1D and 1E determine the trip current for
motor overload protection. The default settings of
parameters 1C, 1D and 1E provide Motor Overload
Protection: Class 10, Trip Current 105% of FLA (full load
amperage) or equivalent.
Motor
Connection Tx
Where 'X' is 1, 2 or 3.
The motor is not connected correctly to the soft starter.
•
Check individual motor connections to the soft starter for
power circuit continuity.
•
Check connections at the motor terminal box.
This trip is not adjustable.
Related parameters: None
Motor
thermistor
The motor thermistor input has been enabled and:
•
The resistance at the thermistor input has exceeded 3.6 k
Ω
for more than one second.
•
The motor winding has overheated. Identify the cause of the
overheating and allow the motor to cool before restarting.
•
The motor thermistor input has been opened.
If thermistors have previously been connected to the
VersiStart p III but are no longer required, use the Thermistor
Reset function to disable the thermistor.
Related parameters: 6J
Network
communication
There is a network communication problem, or the network
master may have sent a trip command to the starter. Check the
network for causes of communication inactivity.
Related parameters: 6G
