3392 !! Fault !! Interruption RS485 Flt>InterrpRS485 The fault occurs if:
- the external display is not correctly connected to the RS485 interface or if
it is disconnected
- at P-INTERFACES/ P-RS485/RktRS485=failure is set and
- a RS485 setpoint source is parameterized.
If there is an external display at the RS485-interface –X51, connect / com-
mission as per description 4BS0751, chapter Communication / External
display.
If there is no external display, recheck the parameter setting in menus
"P-speed default, P-process control, P-T-control, P-current
control:..Setpoint source. If a parameter is on "RS485" or, under
"P-OPERATION", if a parameter is on "…..ext.Bdf" relocate these parame-
ters to another source.
3394 !! Fault !! Thermistor X3:90/91 Flt>PTC X3:90/91 as no. 3194, but not retained
3395 !! Fault !! Safe torque off trig Flt>STO tr. as no. 3195, but not retained
3397 !! Fault !! T-heat sink asymm. Flt>T-Cooler asym as no. 3134, but not retained
3451 !! OFF 2 !! Interruption BUS OFF2>Interrpt.BUS - The fault occurs if:
- the external bus is not correctly connected or if it is disconnected
- at "P-INTERFACES/P-Fieldbus/Rct.BUS=OFF2" is set and
- a BUS-setpoint or actual value resp. operating source is parameterized.
If there is the bus, connect / commission as per description 4BS0751,
chapter Options/Bus-PCBs. Check the status of the bus by means of the
available control-LEDs on the bus-PCB.
If there is no bus at all, recheck the parameterizing at
"P-INTERFACES/op.-source=BUS" or "Reset-source=BUS", or in menus
"P-speed default, P-process control, P-T-control, P-current control" a pa-
rameter is set on BUS. Relocate these parameters to another source.
3452 !! OFF 2 !! BUS Hardware OFF2>BUS Hardware - The fault occurs if:
- the inverter internal connection to the bus does not work correctly
- at "P-INTERFACES/P-Fieldbus/Rct.BUS=OFF2" is set and
- a BUS-setpoint or actual value resp. operating source is parameterized.
If there is a bus, replace the bus-PCB and/or PCB –A1 Control electronics
and contact our service station.
If there is no bus at all, recheck the parameterizing at
"P-INTERFACES/Op.-source=BUS" or "Reset-source=BUS", or in menus
"P-speed default, P-process control, P-T-control, P-current control" a pa-
rameter is set on BUS.
