Functional Safety Parameters That Must Be Set - Mitsubishi Electric MELSERVO-J5 Series User Manual

Changing the password
Set a password so that the functional safety parameters cannot be changed easily. Once a password is set, the functional
safety parameters cannot be changed without password authentication. No password authentication is required to read the
functional safety parameters. To change the password, follow the steps below.
1.
From the menu of MR Configurator2, select "Change Password".
2.
Set a password. Set a character string of up to 6 alphanumeric characters for the password. Passwords are case
sensitive.
3.
The set password is enabled after the power is cycled or the software is reset.
If the password is forgotten
If the set password is forgotten, initializing the servo amplifier can reset the password.
1.
From the menu of MR Configurator2, select "Initialize Password".
2.
The password is initialized after the power is cycled or the software is reset. The functional safety parameters are
restored to the factory setting, so set them again.

[Pr. PSA01.0 Safety sub-function activation setting]
Set [Pr. PSA01.0] to "1" after confirming the content of the functional safety parameters.
[Pr. PSA01.1 Input mode selection]
Set safety sub-function control by input device or safety sub-function control by network.
[Pr. PSA02 Functional safety setting]
Make the settings in accordance with the system configuration. The recommended parameter settings and achievable safety
level differ depending on the system configuration. Refer to the following for details.
Page 342 Achievable safety level
[Pr. PSA03 SS1/SS2 deceleration monitor time]
Since the SS1 function is used when an error is found during self-diagnosis, set functional safety parameters of the SS1
function in advance. Set a proper value by referring to the following.
Page 357 SS1 function
[Pr. PSA20 Servo motor encoder resolution]
Set the encoder resolution of the connected servo motor. If the set encoder resolution does not match the encoder resolution
of the connected servo motor, [AL. 537 Parameter setting range error (safety sub-function)] occurs. For linear servo motors,
the setting cannot be configured if position monitoring or speed monitoring is not executed.
