FM MOVE EXPLAINED:

The FM Move is fully defined as "Feed to Sensor with Mask Distance". The drive will make a typical Feed to Sensor (Registration) move, but with the added flexibility

of adding a "Mask" distance, which means that the sensor is ignored for distance DC from the start of the move.

This is useful if you were working on a part that has a hole or pocket in it, which would normally trip the sensor.

This way, by putting in a DC value that is close to the dimension of your part, the sensor is ignored until DC has been passed, so the next signal from the

sensor would be the actual end of the part. This would trigger the drive to make the "DI" portion of the move, which will be the distance

from the sensor input to the position at which the motor stops.

In the example below, the depicted part is a brake rotor, with a large mounting hole in the center. We need to "mask" (or ignore) the sensor until it is past this hole, then

it can correctly read the edge of the part, which will trigger the "DI" part of the move, and the drive will continue at velocity then decel to a stop, or start the

decel immediately, depending on the values for DI and DE.

Remember, the drive is an open-loop stepper system. Just because you put in a value 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"

DC

"Distance Change", this is the "mask" distance (sensor is ignored)..

"DC60000"

SA

Saves parameters in drive.

"SA"

FM1F

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.

"FM1F"

FM1F sets the drive move (FM), and tells the drive to look at the signal at input #1 (Step terminal) for the "falling edge" (F) of the signal.
