10. COMMUNICATION FUNCTION (MITSUBISHI ELECTRIC GENERAL-PURPOSE AC SERVO PROTOCOL)
10 - 21
10.2.4 Test operation mode
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.
(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.
Command
Data No.
Transmission data
Setting test operation mode
[8] [B]
[0] [0]

Output signal (DO) forced output (Note)
0005 Single-step
feed
Note. Refer to section 10.2.5 for the output signal (DO) forced output.
2) Check of test operation mode
Read the test operation mode set for the slave station, and check that it is set correctly.
