12. COMMUNICATION FUNCTION (MITSUBISHI ELECTRIC GENERAL-PURPOSE AC SERVO PROTOCOL)
12 - 25
12.5.5 Input device on/off
POINT
The on/off status of all devices in the servo amplifier are the status of the data
received at last. Therefore, when there is a device which must be kept on,
transmit data which turns the device on every time.
Each input device can be switched on/off. However, when the device to be switched off is in the external
input signal, also switch off the input signal.
Transmit command [9] [2], data No. [6] [0], and data.
Command Data No. Set data
[9] [2] [6] [0] See below.

12.5.6 Disabling/enabling I/O devices (DIO)
You can disable inputs regardless of the I/O device status. When inputs are disabled, the input signals
(devices) are recognized as follows. However, EM2 (Forced stop 2), LSP (Forward rotation stroke end), and
LSN (Reverse rotation stroke end) cannot be disabled.
Signal Status
Input device (DI) Off
External analog input signal 0 V
Pulse train input None
(1) Disabling/enabling the input devices (DI), external analog input signals and pulse train inputs except
EM2 (Forced stop 2), LSP (Forward rotation stroke end), and LSN (Reverse rotation stroke end).
Transmit the following communication commands.
