Trips and Fault Finding
605C Frequency Inverter
Checksum Fail
When the Inverter powers-up, non-volatile memory is checked to ensure that it has not been
corrupted. In the rare event of corruption being detected, the Inverter will not function. This
may occur when replacing the control board with an unprogrammed control board.
Inverter Indications
The failure is indicated by the HEALTH and RUN LEDs showing SHORT FLASH, .
Referring to Chapter 4: “Operating the Inverter” - Reading the Status LEDs, you will note that
this also indicates Re-configuration mode, but this mode (and hence the indication) is not
available to the Inverter unless controlled by an MMI or Comms link.
Because you are controlling the Inverter locally (no MMI or Comms link etc.), the unit must be
returned to SSD Drives for reprogramming, refer to Chapter 8: “Routine Maintenance and
Repair” for address details. However, if you have access to an Operator Station or suitable PC
programming tool, the unit can be reset.
Operator Station Indications (when connected)
The MMI displays the message opposite.
Acknowledge the message by pressing the E key. This
action automatically loads and saves Macro 1 default
parameters and the ENGLISH 50Hz Product Code.
If your unit was using a different Product Code or macro,
you must reload the Product Code of your choice, reload
the macro of your choice, and perform a Parameter Save (SAVE/COMMAND menu) in that
order.
If data will not save correctly, the Operator Station will display a failure message. In this case,
the Inverter has developed a fault and must be returned to SSD Drives. Refer to Chapter 8:
“Routine Maintenance and Repair" for address details.
