The
command specifies the maximum velocity that can be obtained at full deflection during joystick
JOYVL
mode, with the Joystick Velocity Select input closed (low). The Joystick Velocity Select input function is
defined with the
command. If the Velocity Select input is not used, joystick motion always uses
INFNCi-O
the
velocity.
JOYVH
The joystick velocity must be entered prior to entering joystick mode (
remains set until you change it with a subsequent
flagged as an error, with a message
invalid velocity is entered the previous velocity value is retained.
UNITS OF MEASURE and SCALING: refer to page 16.
Example: Refer to the joystick mode enable (JOY) command example.
JOYZ
Joystick Zero

(multiple inputs per brick may be configured at one time)
Units
B = I/O brick number
i = Location of the analog input on I/O brick (see page 8)
b = enable bit
Range
B = 1-8
i = 1-32
b = 0 (don't zero) or 1 (zero), or X (don't change)

The
command defines the voltage when the joystick is at rest to be the zero-velocity center. Simply
JOYZ
leave the joystick in its resting position and issue a
respective analog inputs as the zero-velocity center. The zero-velocity range about the center is determined
by the
command.
JOYCDB
The
command is an alternative to using the
JOYZ
Example:
1INFNC7-M
; Assign Joystick Release function to brick 1, input 7
1INFNC8-O
; Assign Joystick Velocity Select function to brick 1, input 8
JOYAXH1-17
; Assign analog input 17 to control the axis
JOYVH10
; Max. velocity is 10 units/sec when the Velocity Select
; input (1IN.8) is high (sinking current)
JOYVL1
; Max. velocity is 1 unit/sec when the Velocity Select
; input (1IN.8) is low (not sinking current)
JOYA100
; Set joystick accel to 100 units/sec/sec
JOYAD100
; Set joystick decel to 100 units/sec/sec
;**** COMMANDS TO SET UP USABLE VOLTAGE: **********
1JOYZ.17=1
; This command is executed while the joystick is at rest. It
