FY MOVE
EXPLAINED: |
|
|
|
|
|
|
| The
FY Move is fully defined as "Feed to Sensor with Safety Distance".
The drive will make a typical Feed to Sensor (Registration) move, but with
the added flexibility of |
|
adding a
"Safety" distance, which means that if the sensor is not found by
distance DC from the start of the move, the drive will ramp to a stop. |
|
|
If the sensor is
detected before distance DC is reached, then the drive will perform a normal
FS or Registration move, and will stop at distance DI. |
|
|
|
| This
is useful if you were dispensing labels, for example. If you know the spacing
of the labels, then the sensor should be triggered within a certain window.
If the sensor |
|
isn't triggered within
distance DC, then that would most likely mean the label roll is empty, or at
least that label is missing. |
|
|
|
| This
command is the only one that would have the value DC be larger ( usually much
larger) than value DI. |
|
|
| 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 "Safety" distance ( if sensor not
detected, ramp down and stop). |
|
"DC60000" |
| SA |
Saves parameters in
drive. |
|
"SA" |
|
| FY1L |
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. |
"FY1L" |
|
|
FY1L sets the drive move
(FY), and tells the drive to look at the signal at input #1 (Step terminal)
and wait for it to go "low" (On). |
