Restarting The Drive; Maintenance / Servicing - ABB MicroFlex e190 User Manual

Restarting the drive

Restarting the drive is not part of the STO test or certification processes, but is
included here for convenience.
Action
Deactivate the STO circuit (apply power to the STO inputs).
If the drive holds a Mint program, or is connected to an Ethernet master device that can
enable the drive, it is possible for the drive to restart and begin to control the motor without
further intervention. If the drive does not hold a Mint program, some of the following actions
are necessary, depending on the installation:
• Activate the additional drive enable input (if present).
• In Mint WorkBench (if connected), click the Clear errors button on the System toolbar,
followed by the Drive Enable button on the Motion toolbar.
• Enable the drive from the Ethernet master device (if connected).

Maintenance / servicing

Include the STO operation tests described in
interval checklist on page
to which the drive is connected.
The STO function must be tested by authorized service personnel as frequently as
required by the proof test interval T
checklist on page 200. See also
The STO input terminals do not need any maintenance. Maintain the drive according
to the instructions given in this manual.
The exchange of safety related systems or subsystems must be performed only in a
