8.7 Set Axis Velocity Scale (#29)
Firmware Version:
Version 5.04 and up
Command Number:
29
Data Bytes:
Desired maximum velocity of the T-Series unit controlled by the active axis.
If data is 0, then the active axis will be disabled.
Reply Data:
The reply data is simply an echo of the command data.
Note:
This setting affects only the active axis. See the Set Active Axis (#25) command
for instruction on how to select an axis. This setting is stored in non-volatile
memory and will persist after power-down or reset.
This command is used to set the velocity scale of the active axis. The data represents the desired maximum
velocity corresponding to full displacement of the joystick. When the joystick is moved away from the
neutral position, the displacement is translated into Move At Constant Velocity instruction which is sent to
the unit associated with the displaced axis. See the user’s manual for the device in question for more
information on the Move At Constant Velocity instruction.
The velocity scale setting works in conjunction with the velocity profile setting. See the Set Axis Velocity
Profile (#28) command for more detail.
Setting the velocity scale to 0, will disable the active axis. This prevents the joystick from sending any
instructions in response to displacement of that axis. This is useful when the user wants to execute a
program from the computer, and does not want the joystick to be accidentally moved.
The default velocity scale for all three axes is 2922.
