Axis Parameters
Trio Motion Technology
SPEED
Type:
Axis Parameter
Description:
The
SPEED
axis parameter can be used to set/read back the demand speed axis
parameter. The speed is returned in units/s. The demand speed is the speed
ramped up to during the movement commands
MOVE, MOVEABS, MOVECIRC, FOR-
WARD, REVERSE, MHELICAL and MOVEMODIFY
.
Example:
SPEED=1000
PRINT “Speed Set=”;SPEED
SRAMP
Type:
Axis Parameter
Description:
This parameter stores the s-ramp factor. This controls the amount of rounding
applied to trapezoidal profiles. 0 sets no rounding. 10 maximum rounding. Using S
ramps increases the time required for the movement to complete.
SRAMP
can be
used with
MOVE, MOVEABS, MOVECIRC, MHELICAL, FORWARD, REVERSE
and
MOVE-
MODIFY
move types.
Note:
The
SRAMP
factor should not be changed while a move is in progress.
SSI_BITS
Type:
Axis Parameter
Description:
This parameter is only used with the SSI Absolute daughter board. It is used to set
the number of data bits to be clocked out of the encoder by the axis hardware. The
maximum permitted value is 24. The default value is 0 which will cause no data to
be clocked from the SSI encoder, users MUST therefore set a value depending on the
encoder type.
If the number of SSI_BITS is to be changed, the parameter must first be set to zero
before entering the new value.
Example:
SSI_BITS AXIS(3)=12
SSI_BITS AXIS(7)=21
