U511 User’s Manual Programming Commands
Version 1.1 Aerotech, Inc. 5-81
5.5.72. SLEW
The SLEW command is used in conjunction with the joystick option to provide
immediate axis control. While in the joystick slew mode, the following functions are
available:
Joystick A Button Toggles pairs of axes/drives between h1 v1 and h2 v2 as
specified.
Joystick B Button Selects between high velocity, low velocity, and absolute
positioning mode. Refer to axis parameters x50
(“Joystick high speed”), x51 (“Joystick low speed”), and
x52 (“Joystick absolute scale”).
Joystick C Button Cancels previous joystick command. Same as the SLEW
C command.
If more than one contour plane is enabled when the SLEW command is issued, the
UNIDEX 511 processes them one at a time. Refer to PLANE for information concerning
contour planes.
When SLEW mode is canceled, the absolute and relative position registers will not reflect
the axis positions. They can be updated with the “Software Position” command. Refer to
the SOFTWARE command description for additional information.
Following use of the joystick to slew the axes to the desired position, the slew mode may
be terminated by depressing the joystick's C button. (Refer to Figure 5-10.) The
UNIDEX 511 will resume processing with the next command in the queue buffer.
