REGULAR CHECK

A comprehensive check must take precedence if it coincides with a regular check.
A regular check is intended only to demonstrate the STO is functional. It will not always detect the loss of a single channel. It is therefore important for
the user and / or machinery builder to determine the frequency of the comprehensive checks based on their knowledge and application of the machine.
The following tests should be performed:-
STO test
1 Ensure that no harm can come to personnel or equipment if the motor turns.
2 Apply +24V DC to terminals X10/01 and X10/03.
3 Apply power to the drive.
Try to start the drive with a non-zero setpoint. This setpoint value will be
referred to as SPT1 for brevity in these tests.
4
Leave this set throughout all tests.
Disconnect X10/01 and X10/03 within 1 second of each other and leave
5
disconnected for approximately 5 seconds (must exceed 3 seconds)..
6 Re-apply 24V to X10/01 and X10/03.
7 Try to restart drive.
Stop the drive.
8
Test is complete.
