5.5 Saving a Verified Parameter File to the Option Board
A verified parameter file can be saved to the option board without executing the whole parameterization process. Saving a verified
parameter file can be done with the service level password. Modifications to a verified parameter file invalidate the verification and
the verification must be done again.
Procedure
Open the verified parameter file. Make sure that also the PC tool confirms that it is verified.
Check the parameters in the opened file. For example:
Make sure that the I/O assignments match the wiring.
Make sure that the correct safety functions are parameterized.
Read the parameter file comment.
Press "Save" to begin the saving process.
Select an AC drive and connect to it.
Save the parameter file and start testing the system.
5.6 Online Monitoring
5.6.1 Viewing the State of the Option Board
In the online monitoring mode, VACON
®
Safe reads the states and values of various signals of the Advanced safety option board
from the AC drive. These signals can be used to monitor the status and execution of the safety features of the AC drive.
The data available for monitoring:
States of the safety functions
States of the digital I/O
Speed values (estimated speed, the measured speed value of the external speed sensor)
Safe fieldbus status
N O T I C E
Online monitoring values are periodically read from the AC drive and the actual values can change between the readings.
5.6.2 Activity Log
The Advanced safety option board logs the events that occur during its operation. This log can be read from the option board and
viewed on the PC tool. Some of the data included in the log is also available when the state of the option board is viewed. The
activity log can be used when it is necessary to analyze the behavior of the option board during a time when the PC tool was not
connected to the option board. The log can be saved to the PC for further use.
The activity log contains
A timestamp that is synchronized to the AC drive operating time
Request signals for safety functions
Active and Reached signals for safety functions
Acknowledgment and Reset signals and their source
Information on the faults that occurred in the option board
The activity log logs the states of the signals when a change occurs in them. The length of the activity log is limited. Depending on
the used safety functions and the frequency of changes in the safety functions, the log may show only a short time. When there is a
situation that requires analysis, read the log as soon as possible to prevent new events from overwriting the critical parts.
The log is not lost when you do power-down to the AC drive.
