Possible cause
Fieldbus settings.
Inside Delta connection.
The motor is too small.
The load on the motor is too small.
(Current is out of measuring
range.)
Power save mode.
Supply voltage is not connected.
•
The RJ45 plug is missing
between the HMI and the
softstarter.
•
RJ45 Network cable is
damaged.
Solution
• Verify that parameters match between the PLC and
the softstarter fieldbus documentation for the fieldbus
protocol used.
Check that the Auto mode bit of the binary output
telegram setting is 1.
• Check if the HMI is set to remote mode.
• Check that the Local Mode digital input on the ABB
FieldBusPlug adapter is set to Remote.
• Check that Fieldbus disable control in DI is not
connected.
• Check that the Fieldbus control parameter is set to
On.
• If the softstarter is connected Inside Delta, the phase
currents displayed are = 58% ( 1 /(√3)) of the motor
current.
• Check that the softstarter corresponds to the motor
size.
• Touch any key on the keypad.
• Connect the Supply voltage according to the circuit
diagram.
• If problem stays, contact your ABB Sales Office.
• Check the RJ45 plug.
• Check the RJ45 Network cable
