Test Operation Mode - Mitsubishi MR-JE-10A Instruction Manual

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

12.5.8 Test operation mode

(1) How to prepare and cancel the test operation mode
(a) Preparing the test operation mode
Set the test operation mode type with the following procedure.
1) Selection of test operation mode
Send the command [8] [B] + data No. [0] [0] + data to select 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] and data No. [1] [2].
b) Reply
The slave station returns the preset operation mode.
(b) Cancel of test operation mode
To terminate the test operation mode, send the command [8] [B] + data No. [0] [0] + data.
POINT
The test operation mode is used to check operation. Do not use it for actual
operation.
If communication stops for longer than 0.5 s during test operation, the servo
amplifier decelerates to a stop, resulting in servo-lock. To prevent this, continue
communication all the time by monitoring the status display, etc.
Even during operation, you can switch the servo amplifier to the test operation
mode. In this case, switching to the test operation mode will shut off the base
circuit to coast the motor.
