-1,073,741,824 to 1,073,741,823. The loaded position is not utilized
until a parameter update occurs.
SET_VEL
Data/direction:
Encoding:
Axis acted on:
Available on:
Double buffered:
Set command velocity
2/write
11 (hex)
current axis

yes
SET_VEL sets the maximumvelocity magnitude used during the S-
curve, trapezoidal, and velocity contouring profile modes. The velocity
is specified as an unsigned 32-bit number with units of counts/sample.
The data word scaling is 1/216. The range is 0 to +1,073,741,823. The
loaded velocity is not utilized until a parameter update occurs.
SET_ACC
Data/direction:
Encoding:
Axis acted on:
Available on:
Double buffered:
Set command acceleration
2/write
12 (hex)
current axis
all axes
yes
SET_ACC sets the command acceleration. When in trapezoidal point-
to-point mode, the acceleration is specified as an unsigned 32-bit
number with units of counts/sample2, represented using 1/216 scaling.
The range is 0 to +1,073,741,823. When in the velocity contouring
mode, the acceleration is specified as a signed 32-bit number with units
of counts/sample2, represented in 1/216 format.The range is -
1,073,741,824 to +1,073,741,823. The loaded acceleration is not
utilized until a parameter update occurs.
This command is used when the profile mode is set to trapezoidal
point-to-point or velocity contouring.
SET_MAX_ACC
Data/direction:
Encoding:
Axis acted on:
Available on:
Double buffered:
Set maximum acceleration
1/write
15 (hex)
current axis
all axes
yes
SET_MAX_ACC sets the maximumacceleration. The acceleration is
specified as an unsigned 16-bit number with units of counts/sample2
represented using 1/216 scaling. The range is 0 to +1,073,741,823. The
loaded max. acceleration is not utilized until a parameter update occurs.
This command is used when the profile mode is set to S-curve
point to point.
SET_JERK

Double buffered:
Set command jerk
2 words
none
13 (hex)
current axis

yes
SET_JERK sets the command jerk used during the S-curve profile
generation mode. The jerk is specified as an unsigned 32-bit number
with units of counts/sample3. The scaling is 1/232. The range is 0 to
2,147,483,647. The loaded jerk is not utilized until a parameter update
occurs.
SET_RATIO
Data/direction:
Encoding:
Axis acted on:
Available on:
Double buffered:
Set command gear ratio
2/write
14 (hex)
current axis
axis #1, #2
yes
SET_RATIO sets the electronic gear ratio used by the trajectory profile
generator. It is used when the profile mode is set to electronic gear. The
gear ratio is specified as a signed 32-bit number represented using
1/216 scaling. The range is -1,073,741,824 to +1,073,741,823. The
specified ratio value is defined as the number of counts of the slave
axis per master axis count with a positive number indicating motion in
the same direction. For example a value of +8000 hex (1/2) will result in
1/2 turn in the positive direction of the slave axis for each full turn of the
will result in 2 turns in the negative direction of the slave axis for each
full turn of the master axis in the positive direction. The loaded ratio is
not utilized until a parameter update occurs.
STOP/CLR_PRFL
Data/direction:
Encoding:
Axis acted on:
Available on:
Double buffered:
Abruptly stop current axis motion
none
46 (hex)
current axis
all axes
yes
STOP, also known as CLR_PRFL in earlier chipset versions, stops the
current axis by setting the target velocity to zero. This function will not
be performed until a parameter update occurs. After the update occurs
the axis trajectory generator will stop and the motion complete bit will
be set. This command is useful for stopping the axis abruptly.
