long CamOpenTable(long table_number,long size,long order);

Opens the cam table.

• The table_number argument specifies the table number. Valid

tables are one, two, and three.

• The size argument specifies the number of segments to be

allocated.

• The order argument specifies the precision of the segments. Valid

values are one through nine, inclusive.

Returns 0 if successful, or -1 if there was an error.

A cam table cannot be opened if it is active or queued.

Using higher values for order generates better approximations to the

profile functions but it also requires more memory. The amount of

memory allocated is roughly equal to size*(order+2) words. Using a

value of five provides a good balance between precision and memory

usage.

long CamPhaseAbort(void);

Aborts phase adjustment.

Returns 0 if successful, or -1 if there was an error.

long CamPhaseAdvance(long distance,float time);

Starts phase adjustment in positive direction.

• The distance argument defines the amount of adjustment in master

counts.

• The time argument defines the duration of the adjustment in

seconds.

Returns 0 if successful, or -1 if there was an error.

long CamPhaseRetard(long distance,float time);

Starts phase adjustment in negative direction.

• The distance argument defines the amount of adjustment in master

counts.

• The time argument defines the duration of the adjustment in

seconds.

Returns 0 if successful, or -1 if there was an error.
