Test Operation Mode - Mitsubishi MR-JE-200A Instruction Manual

10. COMMUNICATION FUNCTION (MITSUBISHI ELECTRIC GENERAL-PURPOSE AC SERVO PROTOCOL)

10.2.4 Test operation mode

(1) How to prepare and cancel the test operation mode
(a) Preparation of the test operation mode
Set the test operation mode type with the following procedure.
1) Setting of test operation mode
Transmit the command [8] [B] + data No. [0] [0] + data to set the test operation mode.
2) Check of test operation mode
Read the test operation mode set for the slave station, and check that it is set correctly.
a) Transmission
Transmit command [0] [0] + data No. [1] [2].
b) Return
The slave station returns the preset operation mode.
(b) Cancel of test operation mode
To stop the test operation mode, transmit the command [8] [B] + data No. [0] [0] + data. Turn off the
servo amplifier before switching the operation mode from the test to the normal.
POINT
The test operation mode is for checking an operation. Do not use it for an actual
operation.
If communication stops for 0.5 s or longer during the test operation, the servo
motor decelerates to a stop, resulting in servo-lock. To prevent this, keep the
communication all the time by checking the status display, etc.
The test operation mode can be started even in operation. In this case,
switching to the test operation mode will shut off the base circuit to coast the
servo motor.
