DESCRIPTION OF THE ACTUATION
The ground fault is detected through the
instantaneous imbalance between the supply
phases current.
When there is no current synchronism pulse
at the initial start.
When the voltage between phases is higher
than programmed during the programmed
time. As reference the nominal line voltage
is used.
When the value of the Soft-Starter output
voltage is wrong, while the motor is disabled.
When the current value in one of the phases
is above 30% of the Soft-Starter rated current
with the motor stopped, that is, without the
Run command.
When the setting of an incompatible para-
meter has been programmed.
When the Soft-Starter does not receive tele-
grams from the master during a time longer
than has been programmed at P314.
When the Fieldbus communication board is
active and Communication with the Master
is inactive.
Soft-Starter could not access the Fieldbus
communication board during the initialization
or during operation.
When the electrical connection between the
Keypad and the SSW-06 has been interrup-
ted.
POSSIBLE CAUSES
The values adjusted in P618 and P619 are too low
for the application.
Ground fault at the motor connection.
Ground fault in the motor.
Loose contact of the motor connections.
Thyristors or internal By-pass relays are
short-circuited.
P150 setting wrong.
The line overvoltage value (in percentage of P400) is
higher than the programmed in P602, longer than the
time programmed in P603.
Transformer tap selected with too high voltage.
Capacitive power supply with too low inductive load.
Loose contact in the motor connection.
Wrong motor connection.
P150 setting wrong.
Short circuit in some thyristor or relay of internal by-pass.
External short circuit in parallel with the Soft-Starter
power.
Defect in the current analog reading.
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 confi
-
guration problem.
Communication cables are not installed correctly.
When the Fieldbus communication board is not being
used, program P309=0.
The Profibus master is in Stop, or P310=1 when the
bit 6 of the control word is not being used.
For more details, please refer to the Fieldbus Commu-
nication 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.
Loose contact in the Keypad connection.
Electrical noise (electromagnetic interference).
