Using command [9][0], disable the output signals in advance.
(a) Choosing DO forced output in test operation mode
Transmit command [8][B] data No. [0][0] data "0004" to choose DO forced output.
0 0

4: DO forced output (output signal forced output)
0 4
(b) External output signal ON/OFF
Transmit the following communication commands.

To perform operation after performing the motorless operation, issue a command from the controller.
(b) Canceling motorless operation
The motorless operation cannot be canceled in the same way as the test operation mode (transmit
command [8][B] + data No. [0][0] + data "0000"). To cancel the motorless operation, power on the servo
amplifier and shift to the CC-Link operation mode beforehand.
