FS MOVE EXPLAINED:

The FS Move is fully defined as "Feed to Sensor". The drive will ramp up to velocity, and stay at that velocity until the assigned input is triggered. When the input

is sensed, the drive will move accordingly so that it reaches distance DI. Depending on the settings, the drive could continue at velocity for a noticeable length of time,

or it could start the ramp down very quickly. It depends on the values entered for VE (Velocity), DI (Distance), and DE (Decel).

This is a very useful move, since the drive stays in motion until the input is triggered.  For example, if parts come out of a machine on an irregular basis, the drive could

run a conveyor that the parts fall on, and once the FS command has been sent to the drive, it would continue feeding the conveyor until a part was discharged

onto the conveyor, the part would trigger the sensor, and the drive would stop the part at distance DI after the sensor input. So no matter when the part falls

onto the conveyor, it ends up at the same position.

For another example, imagine you are printing on slightly irregular lengths of cardboard or paper. After printing, you want to cut each sheet to make sure they are the same length.

By using the FS move, the sensor could pick up the leading edge of each sheet, and if we had setup our system so that the DI value was 110,000 steps, then the

motor would turn 11 revs total ( let's assume that is equivalent to 11.00 inches), and the sheet would be properly positioned, ready to be trimmed to uniform length.

Remember, the drive is an open-loop stepper system.

Even though a valid value is entered, that doesn't mean

the drive/motor can achieve your desired move.

MD

"Motor Disable", always do this when changing Command Mode settings.

"MD"

CM21

"Command Mode 21", makes sure the drive is set to Point-to-Point positioning mode.

"CM21"

AC

"Accel", sets the accel, which will apply to the starting ramp. Both Accel and Decel are independently adjustable, if desired.

"AC2"

DE

"Decel", sets the decel, which would apply to both changes decel ramps.

"DC2"

VE

"Velocity", sets the peak velocity of the move.

"VE3"

EG

"Electronic Gearing", this is the steps per rev setting of the drive

"EG1000"

ME

"Motor Enable", enables the motor for motion

"ME"

DI

"Distance", this is the overall move distance

"DI90000"

SA

Saves parameters in drive.

"SA"

FS1L

Initiates the move. After the other settings are loaded to the drive, this is the only command required for the drive to make the move.

"FS1L"

FS1L sets the drive move (FS), and tells the drive to look at the signal at input #1 (Step terminal) for the signal to go "low" ( On).
