POSSIBLE CAUSES
Setting attempt of an incompatible parameter.
See Table 4.2.
The Timeout programmed at P314 is longer than the
time programmed between the telegrams sent by
the network master.
The master does not send telegrams cyclically,
program P314=0.
When the serial communication is not used,
program P314=0.
For more information, please refer to the
Soft-Starter SSW-06 serial communication manual.
Communication error between the Fieldbus
Network Master and the Soft-Starter
SSW-06.Master configuration problem.
Communication cables are not installed correctly.
When the Fieldbus communication board is not
being used, program P309=0.
For more details, please refer to the Fieldbus
communication manual of the Soft-Starter SSW-06.
Data exchange problems between the Soft-Starter
SSW-06 and the Fieldbus communication board.
Wrong configuration of the Fieldbus communication
board, programmed at P309.
Board connection problem.
When the Fieldbus communication board is not
being used, program P309=0.
For more details, please refer to the Fieldbus
communication manual of the Soft-Starter SSW-06.
Bad contact in the Keypad (HMI) connection.
Electrical noise (electromagnetic interference).
Excessive load on the shaft.
Load cycle too high (large number of starts and stops
per minute).
Ambient temperature too high.
Bad contact or short-circuit (resistance <100) in the
wiring from motor thermistor to X1 terminal of the
CCS6 board.
P268 is wrong.
Stalled motor, locked motor.
Bad electric contact in the current transformer cables
or control board connection cables.
A thyristor or contactor in short-circuit.
Problems in the control board.
Time programmed at P102 is shorter than required.
The programmed current limit at P110 is too low.
The programmed current limit at any point of
current ramp is too low.
The programmed torque limit at any point of the
torque control is too low.
Stalled motor, locked rotor.
The motor rated current that has been programmed
at P401 is wrong.
The time programmed at P102 is shorter than the
required to start the motor by voltage ramp.
The transformer that supplies the motor may be
saturated and requires too much time to recover
from the starting current.
Stalled motor or locked rotor.
For special motor that support this working
condition you can set P617=0.
