CD - CPU Dump

Purpose:
Returns the status of the CPU and the database. Call CD if:
ƒ

The SR report indicates a CPU exception.

ƒ

The MF report indicates a CPU exception.

ƒ

An attempt to start the motor returns a “Bad database” error code.

The CD report returns a string similar to the following:
Null Address=0
Failure Address=0
Called Handler=none
Database Status:
Database OK
Sub Processor Status:
0

where:
ƒ

“Null Address” is the code address at which a CPU exception occurred. A “0”
indicates a normal condition.

ƒ

“Failure Address” is the code address at which a stack overflow has occurred. A “0”
indicates a normal condition.

ƒ

“Called Handler” is the type of CPU exception that occurred. A “none” indicates a
normal condition.

ƒ

“Database Status” indicates if the recent database check at MO=1 — at power up or
during a save (SV) — revealed a consistent database. “Database OK” indicates the
normal condition.

ƒ

“Sub Processor Status” indication is relevant only for SimplIQ models supporting an
absolute position sensor (“A” drive type). It indicates if the inquire for position
(single-turn and multi-turn position values) at power up or during another process
causes a communication loss between the two processors or between the drive and
the position sensor. In both cases, the absolute position readout will fail to update.

“-1” - indicates that Absolute encoder setting parameters (AB[] command) were

not initialized by the Composer or drive is in the reset condition

“0” - indicates that the initialization process was passed successfully

“1” - indicates a communication failure during the initialization process. Verify

the hardware connection of the absolute feedback type.

“2” – indicates a time-out response caused most likely by the sub-processor

running in the boot mode.

“3” – absolute sensor type isn't supported by the firmware

“6” – indicates that an absolute position inquire was performed before an

initialization process

“7” – indicates a communication failure between the processors during an

absolute position inquire
