4. SAFETY OBSERVATION FUNCTION

4.3.4 Test operation

(1) Summary
When using MR-D30, parameter setting is necessary for using the test operation. Set [Pr. PSA02
Functional safety unit setting] to "_ _ _ 2". The diagnosis function and safety observation function are
partially disabled in the test operation mode. The mode can be used for the JOG operation, positioning
operation, machine analyzer, etc. for when the startup of safety devices is not complete. Note the
following for test operation mode.
(a) Set the test operation mode. For details of the test operation mode, refer to each servo amplifier
instruction manual.
(b) I/O will not be diagnosed.
(c) Operate with great care because the safety observation function is disabled.
(d) If the servo motor operates abnormally, use EM2 (Forced stop 2) to stop it.
For details of the test operation, refer to each servo amplifier instruction manual.
To stop the test operation, set [Pr. PSA02 Functional safety unit setting] to "_ _ _ 0" or "_ _ _ 1"
according to your system configuration, and cycle the power.
(2) DO forced output
Output signals of DO1_ to DO4_ can be switched on/off forcibly and independently regardless of servo
status. This function is used to check the wirings of signal output, etc. Exercise control on the DO forced
output screen of MR Configurator2.
This function can be used only when [Pr. PSA02 Functional safety unit setting] is set to "_ _ _ 2" (test
operation mode).

4.3.5 Unit replacement

When an MR-D30 that has already been attached to MR-J4-_-RJ servo amplifier once is attached to the
other MR-J4-_-RJ servo amplifier, [AL. 7A Parameter setting error (safety observation function)] will occur.
To use the MR-D30 with other MR-J4-_-RJ servo amplifier, initialize the password by the password
initializing function of MR Configurator2. When the password is initialized, all the parameters will be
initialized. [AL. 7A Parameter setting error (safety observation function)] occurs until the parameters are set
again.

4.4 I/O function

4.4.1 Input device

(1) Summary
For the safety observation function control by network, input devices cannot be used. The input devices
of MR-D30 have the following characteristics.
(a) Input device selection
Any device can be assigned to DI1_ to DI6_ with parameters.
(b) Duplication of the input wiring
The input error will be detected immediately by verifying input signals with duplicated wirings.
