MV
Description
Indefinite move command.
Syntax
xx MV nn
Remarks
This command is used to move an axis indefinitely. If this command is issued when an axis’
motion is in progress, the controller will ignore this command and generate “MOTION IN
PROGRESS” error message.
Issue a Stop (ST) or Abort (AB) motion command to terminate motion initiated by MV
Argument Value Description
xx 1 to 2 Axis number
nn + Move desired axis in positive direction
- Move desired axis in negative direction
Example
1MV+ (Move motor 1 indefinitely in positive direction)
AB (Abort /halt motion)
2MV- (Move motor 2 indefinitely in negative direction)
2ST (Stop motion)

MZ
Description
Find nearest index search.
Syntax
xx MZ nn
Remarks
This command is used to move an axis to its nearest Index in positive or negative direction.
The controller will automatically stop the axis after crossing the index. If this command is
issued when an axis’ motion is in progress, the controller will ignore this command and
generate “MOTION IN PROGRESS” error message.
The controller executes a unique sequence of motion in order to locate and finally stop the
positioner at a repeatable Index position. The repeatability precision depends mostly on the
repeatability of the Index itself and ability to stop and hold final position. It is not unusual for a
Find Index function to be repeatable to within 4 encoder counts (e.g., 8410 rotary stage).
The MZ motion status can be monitored using the Motion Done (MD?) command.
NOTE: The controller will NOT stop motion until it finds the Index signal transition.
Send the Stop (ST) or Abort (AB) motion command to terminate motion.
NOTE: The Find Index function is compatible with 8410 positioner.
