Viewing Trip Conditions

The following function blocks (MMI menus) can be viewed to investigate trip conditions:

Checksum Fail

When the drive powers-up, non-volatile memory is checked to ensure that it has not been
corrupted. In the rare event of corruption being detected, the drive will not function. This may
occur when replacing the control board with an unprogrammed control board.

Drive Indications

DEFAULT
Referring to Chapter 4: "Operating the Drive" - 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 drive unless controlled by an MMI or Comms link.
Because you are controlling the drive locally (no MMI or Comms link etc.), the unit must be
returned to Parker SSD Drives for reprogramming, refer to Chapter 7: "Routine Maintenance
and Repair". However, if you have access to an keypad or suitable PC programming tool, the
unit can be reset.

Keypad 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 keypad will display a failure message. In this case, the drive
has developed a fault and must be returned to Parker SSD Drives. Refer to Chapter 7: "Routine
Maintenance and Repair".
