JENA * Returns the value of joystick enabled status
Write:
JENA=3 * Enables both X and Y axes.
Notes:
- Do not enable joystick operation while the analog input port connection is opened. If you activate the joystick motion in the open status, the detected voltage will deviate from the invalid range, and the axis may start unexpected motions.
- When the power is turned on, the command pulse counter is "0", but it may be in a position different from the reference position of the soft limit value. If you operate the joystick in this status, you may hit a mechanical limit before the software limit works. When operating with a joystick, set the reference position "0" in the Homing operation beforehand.
