MM4006 V S D e f i n e the vector acceleration on trajectory
(trajectory acceleration)
Usage I I IMM
■
PGM • MIP
Syntax V S n n or VS?
Parameters
Description n n [double] — Desired trajectory acceleration.
Range n n — > 0 to Max Trajectory Acceleration (MTA).
Units n n U n i t s / s e c ' .
Defaults n n M i s s i n g : M TA .
Out of range: E r r o r C.
Description T h i s command defines the vector acceleration on trajectory that the con-
troller uses to start and stop execution of the trajectory. In association
with the trajectory velocity this will define the necessary time to reach the
trajectory velocity.
NOTE
The controller calculates automatically MTA for the trajectory to execute
(set of trajectory elements entered before this command) one time this
command is entered and limits the vector acceleration to MTA i f the
parameter entered is greater than MTA. It is then advised to read MTA
just before this command with help of the command XU1 and to read
assigned trajectory acceleration after this command with help of the
command VS? or XU.

Rel. Commands
In fact, M TA is defined as the minimum value of maximum allowed X
assigned axis and Y assigned axis accelerations.
If the sign "?" takes place of the nn value, this command reports the actual
trajectory acceleration value.
C — P a r a m e t e r out of limits.
S — Communication time-out.
VV — D e f i n e the vector velocity on trajectory (trajectory velocity).
XU — T e l l the vector acceleration on trajectory (trajectory acceleration).
Example X U 1 I R e a d MTA.
XU10.0 I C o n t r o l l e r tells MTA.
VS8 I D e f i n e 8 units/sec-2 as trajectory acceleration.
XU I R e a d trajectory acceleration.
XU8.0 I C o n t r o l l e r tells assigned trajectory acceleration.
