LinearX LT360 - Get Acceleration Function

56
LT360 Precision Turntable
DLL Programming Manual
■ Class Get (in)
■ Identifier lt_GetAccelFunc
■ Hex Value 0xA2
■ Call LT360LIB_CmdValue(Handle, lt_GetAccelFunc, RtnStr);
■ Returns 'n'
Description
This command returns the acceleration function number (0 to 4). This value
gives the acceleration function which the LT360 will use during step or goto
commands. The acceleration profile is an important feature of the LT360
which enables heavy loads to be moved with minimum disturbance.
The parameter string contains a numeric value such as '1' with allowable
values from 0..4. There are five acceleration functions numbered 0,1,2,3,4.
The names of these profiles are:
0 - Impulse
1 - Flat
2 - Ramp
3 - Sin2
4 - Sin3
For most typical applications acceleration function 1 - FLAT will provide
excellent performance. Because the LT360 controls the acceleration and
deceleration so precisely, very heavy loads can be rotated with ease.
The 0 - IMPULSE function provides the fastest rise time from zero to con-
stant velocity. However it also greatly reduces the maximum load which the
LT360 can rotate, due to its higher acceleration. The acceleration of this
function is about 10X that of the others.
The graphs on the following page show the velocity and acceleration profile
curves for the five different LT360 functions.
