3 Description of functions
[Explanation]
* When the MXT command is executed, the position command for movement control can be retrieved from the personal
computer connected on the network. (One-on-one communication)
* One position command can be retrieved and operated at the operation control time. The operation control time is approx.
7.11 msec with the CR750/CR751 series, and approx. 3.5 msec with the CR800 series (approx. 7.11 msec when user
mechanism is set).
* Operation of MXT command
1) When this command is executed with the controller, the controller enters the command value reception enabled state.
2) When the controller receives the command value from the personal computer, it will output the received command
value to the servo within the next control process cycle.
3) After the command value is sent to the servo, the controller information, such as the current position is sent from the
controller to the personal computer.
4) A reply is made from the controller to the personal computer only when the command value from the personal
computer is sent to the controller.
5) If the data is not received, the current position is maintained.
6) When the real-time external command end command is received from the personal computer, the MXT command is
ended.
7) When the operation is stopped from the operating panel or external input, the MXT command will be halted, and the
transmission/reception will also be halted until restart.
* The timeout is designated with the parameter MXTTOUT.
* One randomly designated (head bit, bit width) input/output signal can be transmitted and received simultaneously with the
position data.
* A personal computer with sufficient processing speed must be used to command movement in the movement control time.
