///////////////////////////////
//
Set the board ID
boardID = 1;
//
Set the axis number
axis = NIMC_AXIS1;
////////////////////////////////
//-------------------------------------------------
//
Is is assumed that the axis being moved has an ADC
channel mapped
//
as its primary feedback. Position is
treated as binary volts.
//
Hence velocity is loaded
in binary volts/sec and acceleration as
//
binary
volts/sec^2.
//-------------------------------------------------
//
Set the velocity for the move (in binary
volts/sec)
err =
flex_load_velocity
(boardID, axis, 10000,
0xFF);
CheckError;
//
Set the acceleration for the move (in binary
volts/sec^2)
err =
flex_load_acceleration
(boardID, axis,
NIMC_ACCELERATION, 100000, 0xFF);
CheckError;
//
Set the deceleration for the move (in binary
volts/sec^2)
