A drive's STO function should always be checked before initial
commissioning, after maintenance, and at regular maintenance intervals.
This check should include the following tests:
No. Activity
1 The STO inputs (control signal terminals 12, 13) are de-
energized. With motor standstill and a stop command
on the DA1 variable frequency drives, InHibit is
displayed (locked state).
2 The STO inputs (control signal terminals 12, 13) are de-
energized and the DA1 variable frequency drive
receives a start command (depending on the selected
mode in P1-13, DI Config Select).
InHibit is displayed (locked state). The motor does
not start.
3 The STO inputs (control signal terminals 12, 13) are
supplied with 24 V DC and the DA1 variable frequency
drive receives a start command (depending on the
selected mode in P1-13, DI Config Select). The motor
starts normally and is controlled by the DA1 variable
frequency drive.
4 The motor is running while being controlled by the
DA1 variable frequency drive and an STO input
(control signal terminal 12 or 13) is de-energized.
InHibitis displayed and the motor coasts.
