57 • TROUBLE SHOOTING
___________________________________________________________________________________________
Cause and trouble shooting
Heat-sink over-temperature. Trips the starter when heat-sink temp. rises above 85˚C.
Check that motor starting is not too frequent.
FAULT
In MAXIMIZED
display Mode
Trips the starter when a N.O contact between Aux. input terminals 13, 14 closes for
over two seconds.
Check contact position and cause of closure.
For more information on programming AUX. IN PROG INPUT refer to section
7.6.9 on
page 42(I/O PROGRAMMING PARAMETERS).
Slow speed time is exceeded.
Check the settings of MAX SLOW SP TIME.
For more information on programming MAX SLOW SP TIME refer to section
7.6.7 on
page 38 (SPECIAL FEATURES PARAMETERS).
Note:
Motor and RVS-DX may be overheated when operating at slow speed for an
Parameters not transferred from RAM to EEPROM or vice versa. After replacing the
EPROM with a new software version or after power up.
Press MODE and ▼ simultaneously, than press STORE and MODE simultaneously.
By doing that, you are loading factory defaults to the RVS-DX. Now program all
parameters into the RVS-DX like in a first start-up procedure.
(If Fault LED is on, press Reset after WRONG PARAMETERS).
If no valid Modbus communication during MODBUS TIME OUT, the HRVS-DN will
trip.
Trip occurs only if the following conditions exist:
• SER. LINK CONTROL is set to ENABLE
• SERIAL LINK NO. is not set to OFF
For MODBUS TIME OUT settings refer to section
7.6.10 page 44.
Trips the RVS-DX if, when controlled via Profibus communication link, the
communication cable is torn or the communication from the PLC is lost.
Note that the occurrence of this fault depends on then “Watch Dog” function of the
Profibus controller.
You must reconnect the wiring and/or the communication with the PLC and wait for a
start command initiated by the PLC.
Trips the soft starter when mains voltage frequency is not within the limits of 45-65Hz.
