VACON® NXP Advanced Safety Options
Operating Guide
If there is room, also add other signals related to the logged situation to the monitoring. They can help to link the Advanced safety
option signals to the drive state and external system events.
10.2 Periodic Testing
The option board does self-tests to determine the correct operation of its subsystems. If faults are found, they are reported to the
user.
If certain inputs or outputs of the option board are not used during normal operation despite having safety functions assigned to
them, a test should be executed periodically to make sure there are no problems related to the cabling.
•
For inputs, it is sufficient to deactivate the input to request the assigned safety function and verify that the safety function acti-
vates. The activation can be verified, for example, from a warning activation in the drive or safe fieldbus reporting the activation
of the safety function.
•
For outputs, the conditions for deactivating and/or activating the output should be fulfilled and external system or equipment
should be used to verify the change in the signal state.
For systems with speed measurement and long standstill time, see
When the motor is at standstill for long periods of time, for example because the STO or the SOS state is maintained in the AC drive,
pay attention to the test intervals.
When the SBC safety function is used, the brake system should be periodically checked for correct operation.
Outside the need for encoder rotation during a long standstill, the Advanced safety option board does not require any periodic
tests or maintenance. The necessity for testing is determined by the application. When you plan the periodic tests, obey the regula-
tions and standards, and take into account the risk and hazard analysis for the application and its safety components.
See the recommendation on periodic testing of the European coordination of Notified Bodies for Machinery (CNB/M/11.050) for
two-channel safety systems with electromechanical outputs in
any electromechanical outputs.

10.3 Resetting the Password
You can reset the passwords used to parameterize the Advanced safety option board from the control panel of the AC drive. Use the
parameter P7.4.1.1.1 to start the password reset. Slot D used as an example in the parameter address (P7.4.1.1.1) is different in other
slots. See
3.8.3 Option Board Menu on the Control
are no other effects. The password reset is included in the factory reset (P7.4.1.1.2).
Procedure
1.
Navigate to the parameter P7.4.1.1.1 Password reset under the menu group G7.4.1.1 Config Settings.
2.
Set the value Reset to the parameter P7.4.1.1.1.
3.
If necessary, set new passwords using the VACON
10.4 Factory Reset
Factory reset of the Advanced safety option board is not connected to the factory reset of the AC drive. The factory reset of the AC
drive does not do a factory reset to the Advanced safety option board, and the factory reset of the Advanced safety option board
does not affect other drive components. The factory reset of the option board can be done from the control panel of the AC drive.
Use the parameter P7.4.1.1.2 to start the factory reset. Slot D used as an example in the parameter address (P7.4.1.1.2) is different in
other slots. See
3.8.3 Option Board Menu on the Control
The effects of the factory reset:
•
The parameter file of the option board is deleted. The STO function stays active until the option board is parameterized again.
•
The passwords are reset to the default value.
•
The activity log in the option board is cleared.
Procedure
1.
Navigate to the parameter P7.4.1.1.2 Factory Reset under menu group G7.4.1.1 Config Settings.
